Abstract

A powerful laser source of radiation with sub-ns pulse duration is required to solve problems of measuring spacecraft orbit parameters and finding exact distances to natural and artificial satellites. The paper presents the Nd:YAG laser which is developed to meet the specified requirements. A “master oscillator and power amplifier” scheme has been used for this laser. The microchip laser with the regenerative amplifier act as a master oscillator with the 5 mJ output pulsed radiation. The repetition rate is about 1000 Hz. Our master oscillator can be used when it is necessary to meet the satellite laser ranging requirements. We obtain 2.5 mJ pulses at the 532 nm wavelength with 50 % conversion efficiency. Lunar ranging requires much more of pulse energy, therefore the two-pass Nd:YAG power amplifier is set. Its output laser energy is 0.4 J with 100 ps pulse duration at the 1064 nm wavelength and 0.3 J with 90 ps pulse duration at the 532 nm wavelength.
