Abstract

Laser range finder is an important device in the field of deep space exploration and earth mapping. Laser is widely used in Laser range finder as an active detection source. After years of development ,the laser index is getting higher and higher, ranging accuracy limits the narrow pulse width output. Detection dynamic range determines the large energy output of laser. The power supply and thermal control ability determined the high conversion efficiency>5%. Therefore the laser has the characteristics of high repetition rate, larger energy , narrow pulse width, high conversion efficiency output. This project has realized the key technologies. The principle verification and engineering prototype of the 10kHz laser have been completed and it has passed the thermal vacuum ,mechanical and thermal environmental tests.
