Laser oscillation in Nd:YVO4 channel waveguides fabricated by ion implantation

In this work, we report continuous laser emission at 1064 nm from channel waveguides fabricated by carbon implantation on a Nd:YVO4 crystal. A quasi single-mode intensity profile was observed, which was caused by defects in the cross-sectional geometry of the waveguides. An analysis of the main laser emission parameters is presented using different output couplers in the laser cavity and the waveguide losses were calculated from these parameters. The laser output shows high stability operating at room temperature, confirming the excellent optical properties of the yttrium vanadate host.
