Application Features
Co2+:MgAl2O4 (Co:Spinel or Co:MALO) crystals serve as an advanced material for passive Q-switching in lasers operating from 1.2 to 1.6 μm wavelength range. The material is particularly effective for:
- 1.54 μm Er:glass eye-safe laser systems
- 1.44 μm and 1.34 μm wavelength applications
- Flash-lamp and diode-laser pumped configurations
- Q-switching without intracavity focusing requirements
