12/19/2016 We just published our first paper in applied physics B on our 243nm laser system.
Abstract:
We demonstrate a continuous-wave ytterbium-
doped fiber amplifier which produces 6.3 W at a wave-
length of 972.5 nm. We frequency-quadruple this source
in two resonant doubling stages to generate 530 mW at
243.1 nm. Radiation at this wavelength is required to excite
the 1S–2S transition in atomic hydrogen and could there-
fore find application in experimental studies of hydrogen
and anti-hydrogen.
