Abstract

We describe the first coherent generation of continuous wave radiation at 121.56 nm. A yield of

3 \times 10^{8} photons / \sec

(0.5 nW) has been achieved by four-wave mixing in mercury vapor. This continuous Lyman-

α

source could be used for laser cooling and precision spectroscopy of both hydrogen and antihydrogen.
