Passive Glasses Laser Cavity Materials S7010N, S7005 and S7000

S7000 is a clear, cerium-doped silicate glass used as a laser cavity material. It is also available to serve as a UV cut-off material. S7005 is a laser cavity material with 5 % doping of samarium oxide. This material is usually thicker than 6 mm. S7010N is a laser cavity material with 10 % doping of samarium oxide. This glass is recommended for most applications. SCHOTT offers a complete line of commercial filter glasses and can produce with a full range of doping levels for specific applications.
