Abstract
Single-frequency Cr,Tm,Ho:YAG (CTH:YAG) microchip lasers pumped by a 785 nm laser diode were reported. Three kinds of pump spot diameters (75, 100, and 120 μm) were investigated for 1 and 0.7 mm thick laser crystals. The maximum single-frequency output power was 32 mW at a crystal temperature of 10°C. The output power against the laser crystal temperature demonstrated the temperature sensitivity of the CTH:YAG laser. The frequency tuning by changing the temperature of the crystal was also investigated. A tuning coefficient of 1.4 GHz/°C was obtained.
