Fiber-Coupled and Short-Pulse Lasers for LiDAR Applications

Monocrom has introduced the LiOM Series of highly unique, fiber-coupled, short-pulse lasers for LiDAR applications. The lasers have been developed for flash, scanning, or indirect time of flight (iToF) LiDAR applications, but they can also be used for other applications.

All the modules are accommodated in the same enclosure and fitted with a 'detachable'fiber. The driver electronics are situated in the housing, and customers can operate the laser by simply providing the required DC voltage supply.

LiOM S9

Designed for LiDAR scanning, the LiOM S9 laser module has a short pulse duration of 6.5 ns with up to 200 kHz pulse repetition rate. The pulses have the highest power of 200 W. As an option, Monocrom can supply this module with fiber collimation optics.

LiOM S6

LiOM S6 is a more robust version of Monocrom’s LiOM S9 model. It has a pulse duration of 100 ns and the highest power of 1000 W. The longer pulses and the higher power affect the pulse repetition rate, which is 10 kHz. The LiOM S6 has been designed for iToF application. Monocrom supplies this model in two versions—1000 W and 500 W peak output power from the fiber.

LiOM S10

The need for uniform illumination of the 'field of vision'and eye safety is crucial here. Gated imaging is the application that comes close to the supposed flash LiDAR. This is the reason why this module is fitted with a square fiber. The laser itself has been developed as a CW and can be modified to different pulse rates and durations with suitable driver electronics.
