Arxiv - Current progress in laser cooling of antihydrogen
Antihydrogen can be synthesized and accumulated in a magnetic trap, its lifetime is 1000 seconds. To achieve a veryhigh precision in experiments is possible only for very cold antihydrogen at temperatures millikelvin. But laser cooling of antihydrogen is difficult to implement in practice. The large recoil energy imposes a restriction on the minimum temperature which can be achieved by simplest methods of laser cooling. The fast and efficient laser cooling requires powerful laser sources in a deep ultraviolet. Pulsed sources with 121.6 nanometer wavelength already exist, but have a small power not sufficient for the fast cooling. The important but complicated technical task is an increase of the intensity of these lasers
