TOPTICA Photonics, Inc.: Simple Operation of a Continuously Tunable Laser with up to 120nm Mode-Hop Free Tuning Range
TOPTICA's continuously tunable laser, the CTL, enables mode‐hop‐free wavelength tuning up to 120 nm with narrow linewidth and highest accuracy. With applications in device characterization, quantum and materials analysis, it is ideal for any application requiring high precision mode-hop free laser operation over a wide tuning range. In this demo, Dr. Rudolf Neuhaus demonstrates how to operate the laser with the fully digital, low noise and drift DLC pro controller using intuitive touch screen controls. To illustrate the convenient features of the laser and DLC pro controller, the system is connected to a spectroscopy cell and the transmission spectra is measured by a photodiode and recorded by the DLC pro with the ability to review the data live and adjust operating parameters accordingly, including the ability to lock the laser to a specific laser line.

See TOPTICA's TOPO In Action!
Join us on Tuesday, March 9 at 1pm EST for a short, informative session to learn more about our Widely Tunable, High Resolution CW-OPO for Mid-IR Spectroscopy & Photonics. This presentation features the TOPTICA TOPO, a CW-OPO that covers the “stretch” region of the infrared from 1.4 - 4um. We demonstrate its ease of use with an automated tuning feature to stabilize the TOPO idler to a target wavelength, and demonstrate our wavelength scanning software which scans the TOPO over a user-defined range.

Join TOPTICA Photonics for an Informative Session Highlighting our Terahertz Systems
You’re invited! Join TOPTICA via Zoom Webinar on Wednesday, March 10 at 4pm EST to learn about our Terahertz products! We provide an overview of optoelectronic terahertz techniques including highly precise systems for frequency-domain measurements, broadband systems for time-domain applications, as well as rapid screening systems for non-destructive testing. For each scenario, representative practical applications will be presented. The presentation will conclude with a demo of terahertz imaging using the TeraFlash Smart, a high-speed time-domain terahertz system with bandwidth out to 4 THz and up to 1600 waveforms/second.

Join TOPTICA Photonics for an Informative Session Highlighting our New iChrome FLE!
You’re invited! Join TOPTICA via Zoom Webinar on Thursday, March 11 at 1pm EST to learn about our new iChrome FLE! Instrument stability and reliability are key aspects for reproducibility in life sciences. When it comes to laser light sources for Microscopy there are many factors that degrade overall performance. While varying or declining intensity due to alignment issues is one of the most prominent challenges, other sources of degraded performance need to be considered. Cross-talk from acousto-optical modulators (and their limited extinction ratio), as well as laser “noise” sources from fast intensity fluctuations are often overlooked. Other considerations such as service lifetime and operational stability can also be concerns. We will show how the new iChrome FLE bypasses most of these challenges due to its unique optical design, and conclude with a system demo. Register at:

See TOPTICA's DLC HoloLitho in Action!
Join us on Wednesday, March 10 at 1pm EST for a short, informative session to learn more about our DLC HoloLitho! While Kr+ gas ion lasers have been used in industry for holography & lithography applications for over 25 years, their costly operation and maintenance make them less than ideal ongoing production. We demonstrate the performance of the DLC Holo-Litho and highlight the unique features, that insure superior performance in comparison to Kr+ ion gas lasers while delivering a lower total cost of operation.

Schedule a Meeting with a TOPTICA Expert!
With virtual trade shows, the human connection is missing. Collaborators, colleagues and companies find a challenge in recreating those serendipitous meetings that make conferences so productive and rewarding. We miss the opportunity to meet you in the exhibit hall at the Moscone Center this year, so we’ve made it easier than ever to schedule time with our team of product managers, subject matter experts and sales staff using this link: Find time to connect and challenge us with your application!
