Product Description
Co2+:MgAl2O4 Single Crystal Substrate Overview
Double Side Polished Co2+:MgAl2O4 single crystal substrate is an advanced material specifically designed 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 lasers while maintaining excellent performance at 1440 nm and 1340 nm wavelengths.
Key Performance Advantages
- Specifically suitable for 1.54 μm eye-safe laser applications
- 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
