摘要：
Employing graphene oxide as a saturable absorber, we experimentally demonstrated a passively Q-switched mode-locked (QML) operation of a Tm,Ho:CaYAlO4 bulk laser. In this case, the absorbed threshold power of Tm,Ho:CaYAlO4 bulk laser was measured as 293 mW by using a 3% output coupler. When the absorption pumping power reached 1 859 mW, it entered a stable Q-switched mode-locked operation state. And when the pumping power reached 3 W, the corresponding maximum output power is 213 mW, corresponding to a slope efficiency of 10.1%, the central wavelength of 2 089 nm, the repetition frequency of 100 MHz, and the modulation depth being close to 100%. © 2020, Science Press.
