    Abstract

    We report efficient operation of a KGd(WO4)2 Raman laser pumped by a small, 1W, 532 nm laser module. By changing the output coupler and Raman crystal orientation, more than 8 wavelengths in the yellow-to-red spectral region were generated including 555 nm, 559 nm, 579 nm, 589 nm, 606 nm, 622 nm, 636 nm and 658 nm, ie., the first 4 Stokes orders on the two orthogonal high-gain Raman shifts of KGd(WO4)2. We have also demonstrated spectrally pure output (typically >90% pure) for selected Stokes order with output power up to 400 mW, High slope efficiency (up to 68%) and high beam quality (M2∼1.5) of Stokes output are obtained even at the highest pump power.
