Ultrafast Pump Mirror, High Reflecting, 25.4 mm, Flat, 710-890 nm

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.
