| Abstract: | We report on the first graphene passively Q-switched Ho:YAG ceramic laser with central wavelength of 2,097 nm. Stable pulses of 28–64 kHz repetition rate and 2.6–9 μs pulse widths were generated under 1,907 nm thulium fiber laser pumping. Maximum average power of 264 mW with 9.3 μJ pulse energy was obtained under 3.27 W of pump power. |
