The 10B20UF.20 Ultrashort Pulses High Reflecting Pump Mirror is a precision polished, 1.0 inch (25.4 mm) diameter, flat N-BK7 substrate. It's UF.20 coating is optimized for reflection at 710 to 890 nm, and pump transmission at 488 to 532 nm. This mirror is intended for use as a high reflector while allowing transmission of an Argon or frequency doubled Nd:YAG pump laser. A modified single stack dielectric coating design features maximum bandwidth and minimum pulse dispersion. A broadband visible anti-reflection coating is deposited on the mirror's second surface to allow maximum transmission of pump laser energy in the 488 to 532 nm range.

10 b20uf。20超短脉冲高反射泵浦镜是一种精密抛光,直径1.0英寸(25.4 mm),平面N-BK7衬底。UF.20涂层在710 ~ 890 nm处进行反射优化,在488 ~ 532 nm处进行泵浦透射。这面镜子是打算用作一个高反射,同时允许传输氩或频率加倍Nd:YAG泵浦激光器。改进的单堆叠介质涂层设计具有最大带宽和最小脉冲色散的特点。在反射镜的第二表面沉积一层宽带可见抗反射涂层,以允许泵浦激光能量在488至532纳米范围内的最大传输。
