报道了785 nm激光二极管泵浦的单频Cr，Tm，Ho：YAG（CTH：YAG）微片激光器。对厚度为1 mm和0.7 mm的激光晶体进行了三种泵浦光斑直径（75、100和120 μm）的实验研究。晶体温度为10 ℃时，单频输出功率最大为32 mW。输出功率与晶体温度的关系表明了CTH：YAG激光器的温度敏感性。研究了通过改变晶体温度实现频率调谐的方法。调谐系数为1.4GHz/μ C。
Single-frequency Cr,Tm,Ho:YAG (CTH:YAG) microchip lasers pumped by a 785ánm laser diode were reported. Three kinds of pump spot diameters (75, 100, and 120áμm) were investigated for 1 andá0.7ámm thick laser crystals. The maximum single-frequency output power was 32ámW 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 1.4áGHz/░C was obtained.
