Cobalt-doped magnesium aluminate spinel (Co: MgAl2O4) is a relatively new material for passive Q-switching in lasers emitting from 1.2 to 1.6 μm, in particular, for eye-safe 1.54 μm Er: glass laser, but also works at 1.44 μm and 1.34 μm wavelengths.
High absorption cross-section (3.5×10-19 cm2) permits Q-switching of Er: glass laser without intracavity focusing both with flash-lamp and diode-laser pumping. Negligible excited-state absorption results in high contrast of Q-switch, i.e. the ratio of initial (small signal) to saturated absorption is higher than 10.
Crystro can customize Co: spinel crystals of different sizes according to customer requirements and can provide product coating services
