Abstract Study of LD pumped single longitudinal mode Cr,Tm,Ho∶YAG microchip laser pumped by a 785?nm laser diode（LD） is reported. The pump threshold power of the Cr,Tm,Ho∶YAG microchip laser was 1060?mW and the maximum single longitudinal mode output power was 31?mW. The output power against the laser crystal temperature demonstrated the temperature sensitivity of Cr,Tm,Ho∶YAG crystal. The frequency tuning property of the Cr,Tm,Ho∶YAG microchip laser was also measured by changing the temperature of the crystal, and a tuning coefficient of 14?GHz/℃ was obtained.
