高能量调Q纳秒激光器简述高能量调Q纳秒激光器是一款紧凑高效的空气制冷Q开关激光器,具较高的脉冲峰值功率，非常适合激光诱导击穿光谱LIBS,光致荧光光谱LIF,激光烧蚀和激光遥感等应用。
高能量调Q纳秒激光器可产生100mJ@10Hz激光脉冲,具有超低发散角和较高的倍频效率,***高可到倍频波长211nm,使用OPO后波长可扩展到红外范围。
高能量调Q纳秒激光器采用全空气冷却模式得益于它*越的wall-plug效率，液体不用于传热，因此不需要经常*换冷却液或清洗冷却系统。在内部触发模式下具有较低抖动,可采用脉冲触发用户设备,如果需要，激光脉冲可以从延时发生器外部触发,允许在单次发射（single-shot）或可变脉冲重复模式下操作。
具有以太网接口,方便从电脑上控制和监测激光器,WiFi可选。
这款高能量调Q纳秒激光器可配置1053nm和1064nm基频波长，其中1053nm激光器采用Nd:YLF晶体，可以在单脉冲到***高重复频率范围内工作，而不改变发散角和光束质量。
