10" Co2 MgAl2O4 Single Crystal Sapphire Substrates Saturable Absorber

Double Side Polished Co2+:MgAl2O4 Single Crystal Substrate

1. Co2+:MgAl2O4is a relatively new material for passive Q-switching in lasers emitting from 1.2 to 1.6μm, in particular, for eye-safe 1.54μm Er:glass laser, but also works at 1.44μm and 1.34μm laser wavelengths.
2. 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.
3. Negligible excited-state absorption results in high contrast ratio of Q-switch, i.e. the ratio of initial (small signal) to saturated absorption is higher than 10.

Co2+:MgAl2O4 Single Crystal Substrate Brief Introduction:

• Co2+:MgAl2O4 (Co2+:Spinel or Co:MALO) crystals is a 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 × 10-19cm2) 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.
• We offer the high quality Co:Spinel crystals materials with high optical quality and uniform distribution of Co2+ in laser grade polishing and coatings.

• Suitable for 1540 nm eye-safe lasers
• High absorption section
• Negligible excited state absorptio
• High optical quality
• Uniformly distributed Co
