We have used a femtosecond-written Nd:YAG ceramic optical waveguide as an active media to achieve continuous wave 1.06 nm laser operation. We have obtained output laser power of 40 mW and with laser slope efficiency in excess of 40%. Single mode and stable laser oscillation have been achieved by using the natural Fresnel reflection for optical feedback without the requirement of any kind of mirror or reflective component.
