Abstract
A stable, 22.9 W, 671 nm single-frequency laser using a type II noncritically phase-matched external-cavity frequency doubling is demonstrated. The output power of the fundamental laser is 32.1 W; the corresponding conversion efficiency of frequency doubling from 1342 to 671 nm is calculated to be 71.3%. The ${{\rm{M}}^2}$ factors are measured to be 1.10 and 1.08 in the x and y directions, respectively. To the best of our knowledge, 22.9 W is the highest power obtained for a 671 nm single-frequency laser.
