| Pulsed Laser Diodes with integrated FAC Optics - Highest Power – Smallest Divergence
Pulsed Laser Diodes with integrated FAC Optics
1550 nm pulsed laser diodes (PLDs) are integrated into rangefinder systems, etc. Standard night-vision goggles cannot detect this wavelength. Thus, these PLDs are particularly useful in military laser rangefinders or in friend/foe recognition.
NEW – Integrated FAC optics
The Divergence of the fast axis was optimized by the additional assembly of a fast axis collimation (FAC) lens that is attached directly in front of the laser diode chip. Depending on the lens used, divergences of 5 mrad can be achieved. The integration of both the chip and the lens in a small, hermetically sealed TO-46 housing is particularly advantageous. This design withstands acceleration rates of over 1000 g/ms without a problem, as is required for use in military technology.
This technology is also optionally available with 905 nm pulsed laser diodes. If the wavelength has to be controlled exactly, a thermoelectric cooler (TEC) can be integrated into a TO-8 housing.

| XXL Detector Area in InGaAs Avalanche Photodiodes
InGaAs Avalanche Photodiodes That Have a Detector Area from 80 µm to 350 µm
XXL Detector Area in InGaAs Avalanche Photodiodes
In military applications detection signals are typically very weak. Now that eye-safe pulsed laser diodes have just recently been introduced at 1550 nm for rangefinding applications, the appropriate detector will follow.
Maximum Sensitivity at 1550 nm
These new InGaAs photodiodes detect in the spectral range from 1000 nm to 1650 nm. They peak at 1550 nm!
The so-called IAG series offers much more: In addition to the reliable detector areas of 80 µm and 200 µm, an XXL version is also produced. The massive 350 µm diameter of this series almost overshadows its other features:
• Large bandwidth up to 2.5 GHz
• Smallest dark currents possible
• NEP of typically 0.01 pW/sqrHz
• Damage threshold > 200 kW/cm2
Robust and extremely dynamic, these APDs are delivered in a TO-46 housing. The option of customer-specific solutions is always available with us! |
