A continuous wave 10 W cryogenic fiber amplifier at 1015 nm and frequency quadrupling to 254 nm
R. Steinborn, A. Koglbauer, P. Bachor +4
A stable, continuous wave, single frequency fiber amplifier system at 1015 nm with 10W output power is presented. It is based on a large mode double clad fiber cooled to liquid nit…
High power, continuous-wave, single frequency fiber amplifier at 1091 nm and frequency doubling to 545.5 nm
M. Stappel, R. Steinborn, D. Kolbe +1
We present a high power single-frequency ytterbium fiber amplifier system with an output power of 30 W at 1091 nm. The amplifier system consists of two stages, a preamplifier stage…
A reliable cw Lyman- laser source for future cooling of antihydrogen
D. Kolbe, A. Beczkowiak, T. Diehl +5
We demonstrate a reliable continuous-wave (cw) laser source at the 1\,--2\, transition in (anti)hydrogen at 121.56\,nm (Lyman-) based on four-wave sum-frequency mixing in…
Continuous Lyman-alpha generation by four-wave mixing in mercury for laser-cooling of antihydrogen
D. Kolbe, A. Beczkowiak, T. Diehl +6
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…
