Cooling antihydrogen atoms is important for future experiments both to test the fundamental CPT symmetry by high resolution laser spectroscopy and also to measure the gravitational acceleration of antimatter. Laser cooling of antihydrogen can be done on the strong 1S–2P transition at the wavelength of Lyman-alpha (121.6 nm). A continuous wave laser at the Lyman-alpha wavelength based on solid-state fundamental lasers is described. By using a two-photon and a near one-photon resonance a scan across the whole phase matching curve of the four-wave mixing process is possible. Furthermore the influence of the beam profile of one fundamental beam on the four-wave mixing process is studied.

Splitting Effect

We experimentally report that electromagnetically induced transparency (EIT) in the nonlinear propagation of probe beam, four-wave mixing (FWM) images and in a cascade three-level atomic systems. It is shown that by changing the frequency between pumping fields or dressing fields, respectively, the properties of the measured signals including the intensity and spatial images are affected greatly, including the electromagnetically induced transparency (EIT), Aulter-Townes splitting. By changing the laser frequency we can control the four wave signal, Moreover, the AT splitting effect due to spontaneous emission was also observed under EIT conditions..
