Abstract
Maximum range , as a combination property for evaluating ranging performance of a laser range finder , one of the important factors that affect the operational effectiveness of weapon systems , is paid more and more attention .In order to realize high beam quality and narrow pulse width seed source of the laser ranging system , the electro-optic Q-switch rubidium titanyle phosphate RbTiOPO 4 ( RTP) crystal used to be used in the low-repetition-rate Q-switch was used in high repetition rate laser.A laser at 1064nm was obtained at repetition rate of 25Hz,pulse width of 1.8ns,pulse energy of 1.5mJ,beam quality of M2 <1.3.The results show that this laser provides a qualified seed source for narrow pulse width of 1ns~3ns,pulse energy of 200mJ and no water-cooled all-solid-state laser ranging system.These results are helpful to the laser design with high beam quality and narrow pulse width .关键词
