Q-SPARK的半导体泵浦、风冷、Q开关激光器设计使其可广泛适用于亚纳秒或纳秒峰值脉冲功率需求高达 20MW 的应用场合。
我们优化了我们的创新型免水冷激光晶体末端泵浦技术(water-free laser crystal end-pumping technology)并采用了紧凑节能的封装技术，使其可产生近高斯、低发散的亚纳秒脉冲。可配置被动Q开关Q-SPARK版本，以产生持续时间短至750脉冲能量秒超过5 mJ的脉冲。
E-O Q开关版本在 10-100Hz的范围内可提供脉冲持续时间<1.5ns 能量高达 20mJ的脉冲。
激光器由内建网络服务器通过以太网端口监测控制,提供API以用于用户设备集成。
丰富可选的附件装置可让激光器功能得到进一步的扩展：
> 内置谐波发生器可产生高达四次谐波的输出波长。请参阅数据表了解脉冲能量的规格。
> 使用我们可选配的作用于基波或谐波的电动衰减器可实现脉冲能量的调节
> 通过选配我们具备模拟和/或数字输出接口的脉冲能量监视器即可监测脉冲能量
> 剩余谐波发生器波长可以通过可选的辅助出口连接。
> 可按需求提供光纤耦合输出,请查阅详细规格
