Abstract

The first, to the best of our knowledge, Q -switched operation of a pulsed-laser-deposited waveguide laser is presented. A clad Yb : Y 2 O 3 waveguide was Q -switched using an output coupling mirror coated with a single layer of graphene deposited by atmospheric pressure chemical vapor deposition. During continuous-wave operation, a maximum power of 83 mW at a slope efficiency of 25% was obtained. During Q -switched operation, pulses as short as 98 ns were obtained at a repetition rate of 1.04 MHz and a central wavelength of 1030.8 nm.
