Abstract: We present a simple and compact continuous-wave (CW) 1176 nm laser based on self-frequency Raman conversion in continuous-grown YVO/Nd:YVO composite crystal. With a composite crystal 30 mm in length, a maximum output power up to 1.84 W was achieved at the incident diode pump power of 23.6 W. Corresponding to overall optical conversion, the efficiency was 7.8% and the slope efficiency was 8.5%. The conversion efficiency has been doubled compared with the conventional Nd:YVO CW self-frequency Raman laser . The excellent performance of this laser shows that the long continuous-grown YVO/Nd:YVO composite crystal is promising in the application of CW Raman lasers and ideal for miniaturization.
