Product Description
Double Side Polished Co2+:MgAl2O4 Single Crystal Substrate
Key Applications
Co2+:MgAl2O4 is a specialized material for passive Q-switching in lasers operating from 1.2 to 1.6μm, particularly optimized for eye-safe 1.54μm Er:glass lasers, with additional compatibility at 1.44μm and 1.34μm wavelengths.
Technical Advantages
High absorption cross section (3.5×10⁻¹⁹ cm²) enables Q-switching of Er:glass lasers without intracavity focusing
Negligible excited-state absorption delivers high contrast ratio exceeding 10:1
Specifically designed for 1.54 μm eye-safe laser applications
Superior optical quality with uniform Co2+ distribution
