Q-DOUBLE——双脉冲
Q-DOUBLE是二极管泵浦完全风冷(无水)调q激光器。设计用于产生具有可变时间间隔的两个激光脉冲。它的目标应用是PIV(粒子图像测速)和LIBS(激光诱导击穿光谱)。
激光可以配置为总高达160mJ脉冲能量在10Hz重复率脉冲。在高重复频率配置下，激光在100 Hz重复频率下可产生40J的总脉冲能量。该激光器可以配置为分别从Nd:YLF或Nd:YAG激光晶体发射1053 nm或1064 nm波长的激光。当配置为1053 nm时，激光器可以从单次射击到最大脉冲重复率，而不会显着改变光束发散或轮廓。
我们激光设计紧凑，用户友好的交钥匙系统，需要很少的维护。没有冷冻机，也没有需要放在桌子底下的笨重电源。所有激光电子设备都集成到Q-DOUBLE外壳中，唯一的外部模块是电源适配器，提供12或28 VDC, 50-200 W功率(取决于型号)。
激光控制通过以太网端口通过内置的网络服务器。没有必要安装控制软件-任何电脑甚至手机与现代网络浏览器将能够控制Q-DOUBLE。用户设备的低抖动触发脉冲在内部触发模式下可提供高达450µs的引线。在外部触发模式下，激光脉冲可以由脉冲发生器外部触发。
激光功能可以通过广泛的辅助设备进一步扩展:
- 内置高达四次谐波发生器。
- 基本波长内置电动衰减器。
- 内置脉冲能量监视器与模拟和/或数字输出。
- 独立空气净化装置。
- 红色或绿色光束引导模块。
