Paper Abstract

The increasing use of lidar remote sensing systems in the limited power environments of unmanned aerial vehicles and satellites is motivating laser engineers and designers to put a high premium on the overall efficiency of the laser transmitters needed for these systems. Two particular examples upon which we have been focused are the lasers for the ICESat-2 mission and for the Laser Vegetation Imaging Sensor-Global Hawk (LVIS-GH) system. We have recently developed an environmentally hardened engineering unit for the ICESat-2 laser that has achieved over 9 W of 532 nm output at 10 kHz with a wall plug efficiency to 532 nm of over 5%. The laser has a pulse width of <1.5 ns and an M2 of <1.5. For the LVIS-GH lidar, we recently delivered a 4.2 W, 2.5 kHz, 1064 nm laser transmitter that achieved a wall plug efficiency of 8.4%. The laser has a pulse width of 5 ns and an M2 of 1.1 We provide an overview of the design and environmental testing of these laser transmitters.
