摘　　要：激光器是机载远程光电探测系统的重要组成部分,其性能直接决定系统应用效果。首先从激光测距方程出发,分析不同探测体制以及双波长探测需求;然后针对半导体泵浦固体激光器进行研究,并对不同双波长实现方式进行了分析;最后通过试验验证,实现了高能量双波长激光输出。试验结果表明:通过主动电光调Q技术和LD侧面泵浦共腔谐振技术,可以实现高重频窄脉宽1.064μm和1.57μm双波长激光输出。Laser is an important component of airborne photoelectric long-range detection systemwhose performance directly determines the system's application effect.Firstlybased on the laser ranging equationdifferent detection systems and the requirements of dual-wavelength detection are analyzed.Thenthe semiconductor pumped solid-state laser is studiedand different implementation methods of dual wavelength are analyzed.Finallythe output of high-energy dual-wavelength laser is realized through experimental verification.The experimental results show that the output of dual-wavelength laser of 1.064μm and 1.57μm with high repetition rate and narrow pulse width can be realized by the technologies of electro-optic active-Q-switching and LD side-pumped resonator.
