一种新型的激光测距仪理想光源

A new kind of preferable light source for laser range finder

报道了用光学参量振荡的方法（ＯＰＯ），在Ｎｄ∶ＹＡＧ激光器上，用受激布里渊散射（ＳＢＳ）后向放大输出作泵浦源，获得激光测距仪的理想光源（１．５７μｍ），最大输出能量为２１．６ｍＪ，相应的转换效率为３２％。实验结果与理论分析符合得较好。

In this paper,it is first reported that the optical parametric oscillator(OPO),which is pumped by the back amplified output of stimulated Brillouin scattering(SBS) in the Nd∶YAG laser system,is utilized as a preferable light source of the laser rangefinder(1.57μm).The most output energy of the OPO is 21.6mJ,and the corresponding transmitting efficiency is 32%.The experiment results agree well with the theory analysis.
