Product Description
Co:Spinel Optical Substrate Overview
Co2+:MgAl2O4 (Co2+:Spinel or Co:MALO) crystals represent advanced materials specifically engineered for passive Q-switching applications in laser systems operating within the 1.2 to 1.6 μm wavelength range.
Key Applications
- Primary use in 1.54 μm eye-safe Er:glass laser systems
- Effective operation at 1.44 μm and 1.34 μm wavelengths
- Compatible with both flash-lamp and diode-laser pumping configurations
Performance Advantages
- High absorption cross section of 3.5 × 10-19 cm2 enables Q-switching without intracavity focusing
- Negligible excited-state absorption delivers Q-switch contrast ratios exceeding 10:1
- Superior optical quality with uniform Co2+ ion distribution
- Laser-grade polishing and coatings for optimal performance
