The kilowatt - class laser output have been realized using yb : yag crystal component by diode - pumped 采用中频感应加热提拉法生长yb : yag晶体。
We have researched the theory and experiment on q - switch lasers based on high power diode end - pumped nd : yag crystal to suit the requirement of photoelectric resisting 我们针对光电对抗的应用要求对大功率ld泵浦的调qnd : yag激光器进行了相当深入的研究。
As a new solid laser material in recent years , cr4 + : yag crystal has super advantages , such as big absorption cross section , stable saturable absorption , good heat - conducting and mechanical performance Cr ~ ( 4 + ) yag晶体作为近年来人们发现的新型固体激光材料,具有吸收截面大、可饱和吸收稳定性好、热传导性和机械性能良好等优点。
The cr + : yag crystal has been operated differently as passive q - switching and mode - locking medium by researchers at home and abroad . chapter 2 : researching the q - switching performance of cr4 + : yag crystals with the rate equations Cr ~ ( 4 + ) yag晶体优良的物化性能,使它作为被动调q开关和激光增益介质已实现了不同种类的调q和锁模运转。
A diode pumped cr4 + , nd3 + : yag crystal self - q - switched laser is demonstrated with fiber coupled ld and the imaging system . the pulse laser with 1064 nm wavelength is obtained . the maximum average output power is 3 . 36 w , and the pulse duration is 65 ns , and the repetition rate is 87 khz , the opto - optical efficiency is 15 . 3 % , the slope efficiency is 23 . 8 % 用光纤耦合输出的ld ,通过成像系统会聚,对二极管泵浦的自调q激光器进行了实验研究,得到了平均功率3 . 36w ,脉冲宽度65ns ,重复频率87khz的1064nm脉冲激光。
