短波红外激光在光电侦察与反侦察中的应用

分析了磷化体半导体激光器、掺铒光纤激光器、掺铒固体激光器和基于光学参量振荡器的固体激光器等4种典型短波红外激光器的技术特点与现状，叙述了它们在光电主动侦察和反侦察中的应用。为了满足军用光电系统对激光设备的小型轻量化要求，如何提高半导体激光器、光纤激光器和掺铒固体激光器输出功率/能量，已经成为短波红外激光器发展的主流方向。指出基于光学参量振荡器的固体激光器在远距离选通观察、闪光成像雷达和激光损伤方面的优势依然非常明显，还应进一步提高激光输出能量和激光重复频率。

Applications of SWIR lasers in photoelectric reconnaissance and counter-reconnaissance

Technique characteristics and current situations of four kinds of typical short-wavelength infrared(SWIR) lasers such as phosphorus semiconductor laser, Er-doped fiber laser, Er-doped solid-state laser and solid-state laser based on optical parametric oscillator were analyzed. Their applications in active photoelectric reconnaissance and counter-reconnaissance were given. In order to meet the requirements of military photoelectric system on reducing size and weight for laser devices, how to increase the output power/energy of lasers, such as semiconductor laser, fiber laser and Er-doped solid-state laser became the main development direction of SWIR lasers. Advantages of solid-state lasers based on optical parametric oscillator were still obvious at long-distance gated-viewing, flashlight imaging radar and laser damaging. The laser output energy and repetition frequency should be further improved.
