Dia 5mm Co Spinel MgAl2O4 Q Switching Crystals for 1540nm Eye-Safe Lasers with 3.62 g/cm³ Density and 8.2 Mohs Hardness
Crystro's Co2+:MgAl2O4 crystals enable high-power laser pulse generation without electro-optic Q-switches, reducing package size and eliminating high-voltage power supply requirements.
Co2+:MgAl2O4 is an advanced material for passive Q-switching in lasers operating from 1.2 to 1.6μm, specifically optimized for eye-safe 1540nm Er:glass lasers. The crystal also performs effectively at 1340nm and 1440nm laser wavelengths.
- Specifically designed for 1540nm eye-safe laser applications
- High absorption cross section of 3.5×10⁻¹⁹ cm²
- Negligible excited-state absorption for superior performance
- Exceptional optical quality with uniform Co distribution
- Hard, stable crystal structure with excellent polishing characteristics
