【摘要】 采用LIMO公司150W光纤泵浦模块双向端面泵浦Nd:YLF晶体,使用ZEMAX光学设计软件设计使泵浦光成像比例为1:1.5的四片式耦合光学系统,并利用高速RTP电光腔倒空技术,得到了短脉宽、高稳定性和高光束质量的1053nm激光输出。当重复频率为1Hz注入能量为32mJ时,输出脉冲宽度2.5ns,能量6.5mJ,RMS为1.13%的高光束质量脉冲激光输出。在重复频率200Hz条件下,注入平均功率13.1W,输出功率2.2W,光-光转换效率16.8%,光束质量因子Mx2为1.04、My2为1.05。更多还原

【Abstract】 Using two 150W LIMO fiber pump modules from both sides to pump Nd:YLF crystal,and ZEMAX optical design software to design four-piece coupling system in order to re-image with 1.5× magnification into the Nd:YLF rod,and the use of high-speed RTP electro-optical cavity dumping techniques,has obtained 1053nm laser output with short pulse width,high stability and high beam quality.When the pumped energy is 32 mJ at the repetition rate of 1 Hz,the output energy and RMS are 6.5mJ and 1.13% with 2.5ns pulse width.When the pumped energy is 13.1W at the repetition rate of 200Hz,the output energy is 2.2 W with small M 2 factor where M x 2 is 1.04,and M y 2 is 1.05,and the light-light conversion efficiency is up to 16.8%.更多还原
