20 watt CW 589-nm sodium beacon excitation source for adaptive optical telescope applications

A doubly resonant sum-frequency ring containing an LBO crystal, pumped by 1064 nm and 1319 nm continuous-wave Nd:YAG injection-locked ring lasers, produced a 20 W diffraction-limited, single-frequency, 589-nm beam. A 12 W circularly polarized beam produced a 7.2-magnitude guidestar.
