国外新型电驱动高能激光技术现状与发展趋势

Status and development trend of overseas new type electric drive high-energy laser technology

主要讨论了国外平面波导激光器、固体薄片激光器、浸入式液冷固体激光器、碱金属蒸汽激光器、相干合成光纤激光器等新型电驱动高能激光光源的技术发展现状、关键技术以及未来作为激光武器应用的潜力。它们至少在原理上可以解决当前高能固体激光或光纤激光面临的一些难题,但因为某些缺点或者面临一些待解决技术问题,使其输出功率、光束质量或体积、重量等指标暂时达不到典型高能固体激光或光纤激光的水平。详细讨论了这些新型电驱动高能激光的优缺点,并对其技术发展前景进行初步分析判断。

The status and development trend of overseas new type electric drive high-energy lasers, such as PWG laser, thin-disk laser, liquid immersed solid-state laser, alkali vapor laser and coherent beam combining of fiber lasers, are discussed in this paper. The applied potential of these new type lasers used as light source of laser weapon is analyzed. They can at least solve some problems faced by high-energy bulk solid-laser or fiber laser.Because of some shortcomings or problems to be solved,its output power, beam quality, or volume and weight cannot reach the level of a typical high-energy solid-state laser or fiber laser. The advantages and disadvantages of these new electrically driven high energy lasers are discussed in detail, and their technical development prospects are preliminarily analyzed and judged.
