CO2+Spinnel

Co2+MgAlO4

Co2+:MgAl2O4 crystal is a new material suitable for passive Q-switching. It can be used in laser systems which emits from 1.2 to 1.6 µm wavelengths. It perfectly suits in eye-safe 1.54 µm Er:glass lasers. High absorption cross section allows Co2+:Spinel to be used in Q-switching of Er:glass lasers without intracavity focusing. Optola offers high optical quality Co:Spinel crystals.

Optola offers various sizes and dopings of Co:Spinel crystals.

Standard Dopings 0.05-0.3 atm% are available.
