ABSTRACT
With graphene as a saturable absorber, the efficient and stable 1.4 µm dual-wavelength operation of NdYAG ceramic laser is demonstrated. A maximum total average output power of 601 mW is obtained under the pump power of 22.3 W, corresponding to an optical-optical conversion efficiency of 2.7%. The minimum pulse width and the highest pulse repetition rate are 470 ns and 101 kHz, respectively.
