Abstract
Efficient intracavity and external-cavity KGd (WO4)2 Raman lasers are reported. For an intracavity Raman laser with intracavity frequency-doubling, we obtained 1.7 W at 579 nm and 0.84 W at 588 nm. Using an external-cavity Raman resonator pumped by a 1 W 532 nm laser, we obtained output at more than 8 wavelengths in the range 555 nm to 658 nm with output powers as high as 0.4 W at slope efficiencies up to 68%.
