V3+:YAG Crystals

Novel Material for Q-switching: V3+:YAG crystals are specifically designed for saturable absorber passive Q-switching, enhancing laser performance.

Excellent Ground State Absorption (GSA): With a cross-section of 7×10-18 cm2 near 1.3 μm, V3+:YAG crystals ensure efficient absorption.

Negligible Excited State Absorption (ESA): Enables Q-switching of 1.3 μm and 1.44 μm Nd-lasers without intracavity focusing, compatible with both flash-lamp and diode-laser pumping.

Good Chemical Stability and Thermal Conductivity: V3+:YAG crystals exhibit robust chemical stability and effective heat dissipation.

UV Resistance and High Damage Threshold: The material is resistant to UV radiation and can withstand high energy levels, ensuring durability.

Application Areas: Laser Technology, Nd-Laser Optimization, Medical and Industrial Applications, Scientific Research, Telecommunications, etc.
