Product Description
Co2+:MgAl2O4 Cobalt Spinel Passive Q-Switches
Co2+:MgAl2O4 (Co2+:Spinel or Co:MALO) crystals represent advanced materials designed for passive Q-switching in laser systems operating within the 1.2 to 1.6 µm wavelength range. These crystals are particularly optimized for eye-safe 1.54 µm Er:glass lasers, while also maintaining performance at 1.44 µm and 1.34 µm wavelengths.
Key Technical Advantages
- High absorption cross section of 3.5 × 10⁻¹⁹ cm² enables Q-switching without intracavity focusing
- Negligible excited-state absorption delivers high Q-switch contrast ratios exceeding 10:1
- Superior optical quality with uniform Co2+ distribution throughout the crystal structure
- Compatible with both flash-lamp and diode-laser pumping systems
- Specifically engineered for 1540 nm eye-safe laser applications
