Abstract

We demonstrated a high-power dual-end-pumped passively Q-switched Ho:YAG ceramic laser with a Cr²⁺:ZnS saturable absorber (SA). The influence of the beam diameter on SA on the Q-switched laser performance was investigated. Up to 30.3 W average output power was obtained, to our best knowledge, which is the highest average output power obtained in a Ho-doped passively Q-switched laser. The maximum pulse energy and peak power of 0.94 mJ and 33.5 kW were achieved, when the Cr²⁺:ZnS SA was placed far from the laser beam waist, corresponding to a pulse width of 28 ns and a pulse repetition frequency of 28.8 kHz. In addition, we achieved the highest output power of 40.4 W from continuous-wave Ho:YAG ceramic laser.
