A wavelength-versatile, continuous-wave, self-Raman solid-state laser operating in the visible.

We report a continuous-wave Nd:GdVO(4) self-Raman laser generating wavelength-selectable output in the green-yellow spectral region. The laser combines stimulated Raman scattering (SRS) with intracavity second harmonic and sum-frequency generation (SHG/SFG) to enable "on-demand" operation at any one of three wavelengths, 532 nm, 559 nm and 586 nm, each with output power greater than 3.5 W. Using experimental and numerical modelling results, we show how the highly-interactive, simultaneous non-linear processes of SRS and SHG/SFG may be balanced to achieve stable, selectable multi-wavelength visible operation.
