| 摘 要： | 为了获得能够实用化的大功率355nm准连续全固态激光器,采用同一台双通道射频驱动源对准连续1064nm激光器和532nm激光器中的声光Q开关同时进行调制的方法来实现二者的同步,通过消色差透镜将1064nm光和532nm光同时耦合到Ⅱ类相位匹配LBO晶体进行和频产生355nm紫外激光。在总注入电功率为436W、重复频率为6kHz时,355nm激光最大输出功率6.8W,脉宽为67ns,总转换效率为1.56%。结果表明,采用双波长腔外同步和频的方法可以获得大功率355nm准连续激光输出。

| Abstract: | In order to get practical high power quasi-continuous wave (QCW) laser at 355nm, the 1064nm and 532nm QCW lasers were synchronized by radio frequency drive source with double channels via an acousto-optic modulator. The two wavelengths were coupled into type Ⅱ LBO crystal simultaneously by an achromatic lens and the ultraviolet laser at 355nm was generated. The highest output power of 355nm laser is 6.8W, pulse width is 67ns, conversion efficiency of the 355nm laser is about 1.56% when the injected electrical power is 436W and the repetition frequency is 6kHz. The results show that the high power 355nm QCW laser can be obtained by extra-cavity sum-frequency with double wavelength synchronized lasers. |
