A compact modified SFUR passively mode-locked Nd: YAG laser for satellite ranging

摘要

A compact frequency doubled Nd:YAG laser for satellite ranging is presented. In this system, a self-filtering unstable resonator (SFUR) in new modified configuration and linear colliding pulse mode-locked (CPM) scheme have been adopted. The typical parameters are: Wavelength 532 nm Single pulse energy >= 30 mJ Pulse duration 20 - 50 ps Repetition rate 1 - 5 pps Laser dimensions (main boyd) 132 x 32 x 25 cm Using this system, the Lageos satellite laser ranging have been performed successfully. Up to date, at Shanghai Observatory fixed station and Wuhan transportable laser ranging station the laser has been operating over one year.
