创新的无水激光晶体冷却技术可输出脉冲能量高达100mJ和/或平均输出功率高达4W的高质量激光光束。
Q2系列半导体泵浦全风冷Q开关激光器可广泛适用于需要高峰值功率脉冲的应用场合。
Q2HE系列为Q开关激光器市场树立了新的标准。得益于先进的激光器设计,紧凑、人性化的整合性系统使得激光器几乎无需维护。没有额外的水冷装置和笨重的电源系统占用额外的空间。激光器元件高度集成化在Q2HE腔体内，外部模块仅有一个紧凑型控制盒和27 V DC,50-150W的电源适配器(据型号不同有所差异)。
低于7ns的脉宽和低光束发散使得基本波长可有效转换为最短波长低至211nm的高次谐波。
作用于用户设备的低抖动触发脉冲可提内触发模式。如果需要,激光脉冲可由延迟发生器外部触发。
激光器通过内置服务器经以太网端口进行监控。电脑手机与浏览器均可用于控制Q2(无需安装任何软件)。并可提供用于与用户设备集成的API。
