自20世纪60年代世界上第一台红宝石激光器诞生以来,固体激光器由于具有输出能量高、小而坚固等特点,在激光加工、激光打标、激光测距等方面有重要应用。目前技术发展最成熟的化学激光器是各国研发激光武器系统的首选,但是人们并没有放弃发展紧凑式全固化固体激光器的努力。近年来,国内外在固体激光器的光束质量、冷却技术、泵浦和非线性频率转换等技术方面有了长足的进步,固体激光器为突破强激光武器系统关键技术提供了一种可能途径。
Since the birth of the world’s first ruby laser in 1960s, solid-state lasers have important applications in laser processing, laser marking and laser ranging because of their advantages of high output energy, small size and robustness. At present, the most mature chemical lasers in technology development are the first choice of developing laser weapon systems in various countries, but people have not given up their efforts to develop compact and fully cured solid-state lasers. In recent years, the domestic and foreign technologies such as beam quality, cooling technology, pumping and nonlinear frequency conversion have made great progress at home and abroad. Solid-state lasers provide a possible way to break through the key technologies of the high-power laser weapon system.
