摘要

A high beam quality,all-solid-state Nd∶YAG laser system of high-repetition frequency has been built for Thomson scattering diagnosis.A 1.7 times diffraction limited output beam at a pulse energy of 5 J at 1064 nm is achieved for the first time with a pulse duration of 6.6 ns (FWHM) and a repetition rate of 200 Hz;the output energy stability is 4.9％ peak-to-valley over 6000 shots.
