High power high beam quality in-band pumping picosecond amplification laser system
摘要
利用片状Nd:YVO4晶体为增益介质,研究了部分端面泵浦板条带内泵浦皮秒放大激光系统.发展了部分端面泵浦板条放大器的模式匹配方式,充分结合了带内泵浦和部分端面泵浦板条放大器二者的优势,最终实现了平均功率60.7 W、脉冲宽度16.8 ps、重复频率20 MHz的皮秒激光放大输出,光-光转换效率达到25.3%,当放大输出功率50 W时,光束质量因子(M2)为1.55.
Abstract
The INNOSLAB in-band pumping picosecond amplification laser system is studied with flake Nd:YVO4 crystal.A new method for mode-matching was demonstrated to simplify the amplifier design,integrating the benefits of the in-band pumping technique and the excellent thermal management of the INNOSLAB amplifier design.As a result,an average of 60.7 W,pulse width of 16.8 ps,repetition frequency of 20 MHz laser was achieved with optic to optic efficiency of 25.3%.The beam quality of 1.55 was obtained with 50 W output laser.
