A reliable cw Lyman-$α$ laser source for future cooling of antihydrogen
Lyman-alpha Four-wave mixing Antihydrogen
2011/8/29
We demonstrate a reliable continuous-wave (cw) laser source at the 1 S–2 P transition in (anti)hydrogen at 121.56 nm (Lyman-α) based on four-wave sum-frequency mixing in mercury. A two-photon resonanc...
Physicists at CERN have taken a big step towards making the first spectroscopic measurements on a beam of antihydrogen atoms. The antihydrogen atoms, which consist of an antielectron orbiting an antip...
