摘要
弹载激光主动成像制导技术是现代战争中最重要的精确制导技术之一。其中,弹载激光主动成像激光器的研制,是当前研究的热点和难点。报道了高光束质量弹载1 064 nm激光器,用于激光主动成像。采用二极管端面带内泵浦Nd:YAG晶体,光机电一体化设计,在重复频率100 Hz时,输出激光脉冲宽度为3.005 ns,最大输出单脉冲能量3.36 mJ,输出激光光谱宽度78 pm。带内泵浦和谐振腔的优化设计,保证了良好的光束质量,光束质量因子M2在X方向为1.327,Y方向为1.354。成像结果表明:该激光器的成功研制,对高光束质量一体化固体激光器的参数设计和弹载激光器在激光主动成像中的工程应用都具有一定的指导意义。
Abstract
The missile-borne laser active imaging guidance technology is one of the most important laser guidance technology in the modern war. Among them,the development of the missile-borne active imaging laser is current research hotspot and difficulty. A high beam quality laser of 1 064 nm used in laser missile-borne active imaging was reported. The pulse width of 3.005 ns,the pulse energy of 3.36 mJ and the spectral width of 78 pm at the repetition rate of 100 Hz were obtained by diode in-band end-pumped Nd:YAG crystal and integrated design. The quality of laser beam M2 is 1.327 in X direction and 1.354 in Y direction through in-band pumping and cavity optimization design. Imaging results show that, the successful development of the laser have directive meanings for the parameter design of high beam quality solid state laser and engineering application of laser active imaging.
