Product Description
Co:Spinel Passive Q-Switch for 1.2-1.6μm Lasers
Co2+:MgAl2O4 (Co:Spinel) is an advanced saturable absorber material designed for passive Q-switching in lasers operating within the 1.2 to 1.6 micron wavelength range. This crystal is particularly optimized for eye-safe 1.54μm Er:glass laser systems.
Key Technical Advantages
- High absorption cross section of 3.5×10-19 cm² enables efficient Q-switching
- UV resistant for enhanced durability and longevity
- Excellent chemical stability in various operating environments
- Superior thermal conductivity for stable performance
- High damage threshold exceeding 500 MW/cm²
- Negligible excited-state absorption with contrast ratio >10
