Abstract :
A compact laser for airborne lidar was developed. Laser wavelength is 1047 nm and it´s suggested further to pump SHG and FHG. Pulse energy is 100 mJ Q-switched, repetition rate is 250 Hz. We use efficient pump system with 67% absorption efficiency, fluid coolant for laser rods and laser diodes. The laser head volume is 5 cube decimeter.
