Product Description
Co2+:MgAl2O4 Single Crystal Substrate Overview
Co2+:MgAl2O4 (Co2+:Spinel or Co:MALO) crystals represent an advanced material solution for passive Q-switching in lasers operating within the 1.2 to 1.6 µm wavelength range. This material is particularly optimized for eye-safe 1.54 µm Er:glass laser applications, while also delivering reliable performance at 1.44 µm and 1.34 µm wavelengths.
Key Performance Advantages
- Specifically engineered for 1.54 μm eye-safe laser systems
- High absorption cross section of 3.5 × 10⁻¹⁹ cm² enables Q-switching without intracavity focusing
- Negligible excited-state absorption ensures high Q-switch contrast ratios exceeding 10:1
- Compatible with both flash-lamp and diode-laser pumping configurations
