Laser Beam Dumps
LASER COMPONENTS supplies an extensive range of beam delivery components from partners Haas LTI, ranging from laser process heads to beam expanders and beam directing components such as beam benders and splitter units. There will be times that an unwanted portion of a beam within a system must be blocked in a controlled manner. For this purpose, we supply beam dumps in 19mm, 25mm, 38mm and 50mm aperture configurations to complement various beam delivery aperture ranges. These beam dumps may be brass coated for applications using 1070nm to 10.6um, or copper for 355nm to 532nm. They feature an internal cone structure to more effectively absorb the laser radiation and prevent back reflection and may be either air or water cooled to suit different power levels. A range of mounting configurations are available. Further information https://www.lasercomponents.com/uk/product/beam-dumps-1/

Optical Feedthroughs
LASER COMPONENTS supplies fibre optic feedthroughs which allow optical signals to be easily delivered from one environment to another while preventing any leakage from one side of the barrier to the other side. Both sides can be different, for example one side can be high-pressure (up to 1000 bars), while the other side high vacuum. They can also withstand high temperatures such as +600°C or extremely cold temperatures such as 0.5 K, they can also endure corrosive or radioactive environments. We have a large product range with PM, SM and MM fibres suited for high-vacuum (HV) and ultra-high vacuum (UHV) down to as little as 10–8 mbar l/s. These products are also suitable for high-pressure, up to 1000 bars. Thanks to different sizes such as CF and KF flanges, our feedthroughs can be easily and steadily mounted on a chamber wall. These hermetic fibre optic feedthroughs are available in two main configurations: Bulkhead style equipped with standard FC/PC, FC/APC or SMA connectors where the fibres can be replaced and Inline style having no connector at the flange, but pigtails terminated with connectors. The latter solution allows high packing densities of multiple fibres, at a good price/performance ratio. Some of our hermetic feedthroughs have the advantage of being reconfigurable, meaning that they can be disassembled, reconfigured, and reused for a different application, customization is also available.

FLEXPOINT® Crosshair module used for Radiation Oncology
Volumetric modulated arc therapy (VMAT) is an advanced radiotherapy technique that uses arcs of radiation, rather than individual beams used in other types of radiotherapy. As the machine (called a linear accelerator or linac) moves, it automatically changes the beam shape and treatment dose. To treat patients using the voluntary breath hold technique, a novel couch mounted laser was designed. An additional laser is used along with the traditional way of marking the edge of light field to observe the breath hold for tangential treatments. The FLEXPOINT® 520nm crosshair laser module can be mounted behind the patient to project a crosshair on the patient’s chest allowing the chest wall position (and thereby extent of breath hold) to be visualised on the CCTV camera throughout treatment. The Active Breathing Coordinator™ (ABC) device is used to reduce the amount your organs move by holding your breath for you. A study was approved by the Royal Marsden Committee for Clinical Research and The HRA London-Stanmore Research Ethics Committee. This study demonstrates that with use of the additional laser to verify chest wall position, there is no difference between the voluntary breath hold technique and the use of the ABC machine. ABC is an expensive device costing around £50,000 with disposable mouthpieces costing £150 each. The HeartSpare system costs less than £500 to produce for the laser module with diffractive optics (crosshair), camera mount with pole, 360°piston ball grip head and battery pack. This system can easily be reproduced for other radiotherapy departments and adapted to suit the requirements for individual centres. A detailed article regarding the use of the HeartSpare laser vs the ABC machine was published in Elsevier Clinical and Translational Radiation Oncology journal. A. Ranger, A. Dunlop, A.

Bias Controllers for LiNbO3 Modulators
LASER COMPONENTS supplies the iXblue MBC-LAB and MBC-Board which reduce significantly dither voltage amplitude thanks to the very low noise sensitivity provided. As the Mach-Zehnder interferometer is subject to drift due to thermal changes, thermal inhomogeneity, aging, photo refractive effects or static electrical charge accumulation it is necessary to use the bias controller to avoid the transfer function to move horizontally. The modulation signal is then applied to a changing operating point that can strongly modify the obtained modulation. This new version is characterised by an enhanced stability, a USB communication and a graphical user interface (GUI) are introduced for ease of use. The analogue, digital and pulse MBCs are selected according to the application to perfectly fit the modulator’s behaviour and characteristics. The MBC-AN is designed for analogue applications where a high purity carrier is required. They are easy to implement, and fully automated with their auto-set function. The MBC-DG-LAB controller can be used for any telecom and digital modulation application and it benefits from an auto-set operation for the min modes resulting in simplified use for pulse applications. The MBC-IQ-Lab is an electronic system able to control the MXIQER modulators in a CS-SSB modulation. It is based on the minimisation of the beating harmonic of two small dithers. This system will maintain the harmonic rejection of optical CS-SSB spectrum better than 40dB over tens of hours.

Fibre Lasers and Amplifiers for your Application
LASER COMPONENTS supplies the highest quality fibre lasers and fibre amplifiers for a large variety of applications such as defence, environmental monitoring (remote and in situ sensing), and scientific research. These devices from our partner Lumibird cover a wavelength range from 0.35µm to 2µm and are available either in continuous or pulsed regime. We are proud to offer reliable and reproducible high-quality devices for small quantities and for large mass production. Cold atom sensors have become state of-the-art for metrological applications and we have observed a growing demand for fibre lasers and fibre amplifiers, perhaps due to the heavy funding available for quantum technologies within the UK in that field. These instruments are useful for both fundamental physics measurements and for applied metrology. For this type of research, we provide a robust EDFA which can reach up to 43dBm of saturated output power with a greater reliability. These can accept narrow linewidths with very low phase noise and RIN without distortion along the line, and that is vital for cold atoms for instance to focus on accurate atomic clocks. These devices come with either a single mode fibre or polarisation maintaining fibre as an option. Exceptional build quality benchtop platforms or modules are available depending on your requirement.

Transmission gratings
Alongside a comprehensive range of reflection grating options, LASER COMPONENTS offerS transmission gratings for UV, VIS and IR applications. Transmission gratings are a good solution for those applications benefiting from a fixed grating, such as optical spectrometers. Incident light is dispersed on the rear side of the grating at a fixed angle. Transmission gratings can be very forgiving for certain types of grating alignment errors, and their dispersion characteristics can lend themselves to compact systems utilizing small detector arrays. The gratings are also fairly polarisation insensitive compared with their reflective counterparts. Further information https://www.lasercomponents.com/uk/product/diffraction-grating/

Fluorescence Filters
LASER COMPONENTS offers a comprehensive range of fluorescence filter sets from our partner Omega Optical. Standard sets are available for over 180 dyes and fluorophores. Long pass emission sets and narrowband sets are available for samples with multiple tags. Fluorescence sets typically consist of an excitation filter selecting the range of excitation wavelengths, a dichroic mirror and an emission filter blocking the excitation light. The excitation filter is a band-pass which transmits the desired wavelengths and reflects or absorbs the unwanted wavelengths. The transmitted light is reflected through 45° by the dichroic mirror, directing the excitation wavelengths to the sample and allowing the emission to transmit back though. Finally, the emission filter blocks the excitation light and transmits the desired fluorescence to the detector. These filters produced by Omega Optical are characterised by good blocking out of band and high transmission of desired wavelengths to produce a good quality image with a high signal-to-noise ratio. Filter sets, components, and holders are available for all major microscope manufacturers and models, including Leica, Nikon, Olympus, and Zeiss.

Tested with Photon Precision - Fully Automated Measuring Station Guarantees Highest Quality
Up to twelve COUNT® photon counters can be simultaneously tested for key parameters thanks to Swabian Instruments who has supplied LASER COMPONENTS with a fully automated measurement station. This new technology now allows for continuous process optimisation thus accelerating the quality control of COUNT® modules and improved the measurement accuracy, providing the highest confidence to customers with the lowest possible error tolerance. The measurement station was customised to the precise needs of the Olching, Munich based company. At its heart is the Swabian Instruments’ Time Tagger Ultra, ultilising proprietary data processing architecture making this instrument particularly well suited for time-correlated single photon counting (TCSPC), time interval counting, and coincidence counting. LASER COMPONENTS uses it in conjunction with ultra-short-pulsed diode lasers, high-precision reference power meters, and computer-controlled moving tables. For as many as four wavelengths (405 nm, 505 nm, 670 nm, and 804 nm), performance parameters such as jitter, dark count rate, afterpulsing, dead time, and detection efficiency are measured. COUNT® modules can be tested with and without fibre coupling. The results are digitally logged and used for statistical process control such as trend analysis, to further enhance process improvements. “Through the close cooperation with Swabian Instruments, we obtained a measuring station that is optimally adapted to our processes,” explains Dr. Lars Mechold, technical director at LASER COMPONENTS. “This not only allowed us to further improve the quality control of our products. The optimised manufacturing process means shorter delivery times and better availability for our customers.” Further information https://www.lasercomponents.com/uk/photon-counter/single-photon-counting-modules/

Pyroelectric IR Detector Makes Invisible Flames Visible
The L2200D1810-JH pyroelectric detector from LASER COMPONENTS was developed to make H2 flames, which are invisible to the human eye, visible. For this purpose, the component includes a newly developed filter combination for IR emissions at 2.95µm. This makes it possible to detect hot water molecules produced during the combustion of hydrogen. A built-in reference prevents false alarms. Hydrogen engines are increasingly being considered as an alternative to gasoline and diesel engines. Flame detection is a decisive factor in both burner control in the engine and safety at filling stations.

One Optic Working for Two - Beamsplitter for Multiple Wavelengths with Different Polarisations
LASER COMPONENTS has developed a beamsplitter in which the combined beam of a frequency-doubled laser is split in such a way that 50% of each of the two wavelengths is split off, independent of their polarisations. The polarisation of the split beams remains unchanged. Prior to this new development from our manufacturing facility in Olching near Munich, a two optic system comprising of a traditional beamsplitter and a waveplate were required to achieve this result. This solution significantly simplifies the setup and maintenance of optical systems. The original design is for 1030nm and 515nm. However, wavelengths, polarisation, and reflection/transmission ratios can be individually customised depending on the application.

Balanced Photoreceiver Series HBPR
LASER COMPONENTS would like to announce Femto’s balanced photoreceiver series HBPR, a low noise balanced photoreceiver for detecting the smallest optical difference from DC up to 500MHz. Smaller signals can be detected if the common-mode intensity noise can be reduced, as seen with laser sources for example. Using two matched photodiodes, creating the highest possible common-mode rejection ratio, both observing the same source, one signal is subtracted from the other and the result fed into a low-noise transimpedance amplifier. High rep-rate laser pulses with rapidly changing signal shapes, as in quantum state tomography for example, can be detected. Available as free space or in fibre-coupled formats, these high-speed balanced photoreceivers (HBPR) have switchable gain and bandwidth, switchable AC/DC coupling and broad mechanical compatibility with common optical accessories.
