Abstract
Lasing was realized near a wavelength of 2â¯Î¼m with a compact linear cavity by using a fiber-coupled 792-nm laser diode as the pump source and a Tm3+,Y3+ co-doped CaF2 crystal. By employing broadband graphene oxide (GO) as the saturable absorber (SA), a passive Q-switching Tm,Y:CaF2 laser was implemented for the first time. When the transmission of the output couple (OC) was 2%, the maximum average output power was measured to be 400 mW with a corresponding repetition rate of 20.22â¯kHz and a pulse width of 1.316â¯Î¼s. A maximum continuous-wave (CW) output power of more than one watt was obtained with slope efficiency of 51.5%.
