Abstract
We report continuous-wave yellow emission from a compact Nd:YVO4 self-Raman laser with intra-cavity frequency-doubling in LBO, pumped by a 4.5 W high-brightness diode laser. A maximum yellow output of 140 mW was observed with an overall optical (diode-to-yellow) conversion efficiency of 4.4%, and with a high beam quality (M2∼1.2). A variety of different resonator configurations were investigated in order to achieve low threshold, highest output powers and efficiency, and to investigate amplitude stability.
