摘要
为了获得高功率高重频中红外激光输出,采用LD侧面泵浦技术和高重频调Q技术,获得高功率高重频窄脉宽1064 nm激光输出。通过1064 nm泵浦KTP产生高峰值功率2100 nm激光输出,并抽运ZGP晶体获得12 m J的4200 nm中红外激光输出。通过1064 nm分别泵浦PPLT和PPLN获得8. 3 W的2100 nm激光输出和5. 6 W的3900nm激光输出。试验结果表明:通过高重频调Q技术和LD侧面泵浦技术,可以实现高重频窄脉宽1064 nm激光输出,泵浦非线性晶体可以获得高功率高重频中红外激光输出。
In order to obtain high-power mid-IR laser output with high repetition frequency,the LD side pumping technology and the high-repetition-frequency Q-switching technology are used to obtain 1064 nm laser output with high power,high repetition frequency and narrow pulse width. The 2100 nm laser output with high peak power is produced by the 1064 nm pumped KTP. The ZGP crystal is pumped to obtain the4200 nm mid-IR laser output of 12 m J. The 2100 nm laser output of 8. 3 W and the 3900 nm laser output of5. 6 W are obtained by pumping PPLT and PPLN respectively through 1064 nm. The test results show that using the Q-switching technology with high repetition frequency and LD side pumping technology can achieve the 1064 nm laser output with high repetition frequency and narrow pulse width,and the high-power mid-IR laser output with high repetition frequency can be obtained by pumping the nonlinear crystal.
