Product Description
Co2+:MgAl2O4 Q-Switch Laser Crystal Substrate
Double Side Polished Passive Q-Switch Crystal
Co2+:MgAl2O4 (Co:Spinel) is an advanced laser crystal material specifically designed for passive Q-switching applications in the 1.2-1.6μm wavelength range.
Key Applications & Performance
- Ideal for eye-safe 1.54μm Er:glass laser systems
- Effective operation at 1.44μm and 1.34μm laser wavelengths
- High absorption cross section of 3.5×10⁻¹⁹ cm² enables Q-switching without intracavity focusing
- Negligible excited-state absorption provides contrast ratios exceeding 10:1
