In order to get hundred picosecond laser at 2m band, by using an acousto-optic modulator and Tm:YLF laser as the pump source, an actively continuous wave mode-locked Ho:YAG solid-state laser was obtained at room temperature. The output characteristics of active mode-locked laser were studied. After experimental verification, the parameters of laser were obtained, such as mode-locked pulse repetition frequency of 82.75MHz, the maximal average output power of 1W, wavelength center of 2097.25nm, slope efficiency of 13.3%, and pulse width of about 86.6ps. The results show that mode-locked Ho-doped laser with 100ps pulse width could be obtained by the method of active mode-locked technology.
