Abstract

We demonstrate wavelength-selectable visible emissions from a miniature crystalline laser that combines the stimulated Raman scattering (SRS) effect in an Nd:YVO₄ crystal with intracavity frequency mixing in an angle-tuned beta barium borate (BBO) crystal. The presented laser is operating on demand at any one of three wavelengths in the green-yellow spectral region. Up to 600, 560, and 200 mW output powers at 559, 532, and 588 nm, respectively, are obtained from the continuous wave (CW) laser having a 18 mm long resonator and a 3.8 W laser diode end pumping. The pump threshold for each visible wavelength is less than 0.4 W.
