The 10BV200UF.20 Ultrashort Pulses High Reflecting Pump Mirror is a precision polished, 1.0 inch (25.4 mm) diameter, concave, N-BK7 substrate with an effective focal length of 1000 mm. 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 bv200uf。20超短脉冲高反射泵浦镜为精密抛光,直径1.0英寸(25.4 mm),凹面,N-BK7基片,有效焦距1000 mm。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。
