Abstract

By employing Graphene Oxide (GO) grown by vertical growth method as a saturable absorber, we first demonstrated a stable passively Q-switched mode-locked (QML) all-solid-state Tm:LLF laser. when the LD pump power is higher than 8.58W, the laser operation gets into a stable Q-switched mode-locked state, corresponding mode-locked pulse repetition frequency is 104.2MHz. The modulation depth of mode-locked pulses in the Q envelope is close to 100%. The results show that graphene oxide is a promising SA for QML solid-state laser in the 2μm wavelength
