We demonstrate a highly efficient source of single frequency 266 nm light. A single frequency 532 nm source is frequency doubled in an external ring cavity. Almost 50% internal conversion efficiency in the nonlinear crystal gives a useable output of 660 mW at 266 nm, from 2 W at 532 nm, and up to 1.5 W at 266 nm from 5 W at 532 nm.
