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…
AC-Stark shift and photoionization of Rydberg atoms in an optical dipole trap
F. Markert, P. Würtz, A. Koglbauer +3
We have measured the AC-Stark shift of the Rydberg state of rubidium 87 in an optical dipole trap formed by a focussed CO-laser. We find good quantitative agreement…
Continuous-wave spontaneous lasing in mercury pumped by resonant two-photon absorption
Daniel Kolbe, Martin Scheid, Andreas Koglbauer +1
The first continuous-wave two-photon absorption laser-induced stimulated emission (CTALISE) is demonstrated. The 7^1S-6^1P transition in mercury at 1014nm wavelength is used and se…
Experimental demonstration of single-site addressability in a two-dimensional optical lattice
Peter Würtz, Tim Langen, Tatjana Gericke +2
We demonstrate single site addressability in a two-dimensional optical lattice with 600 nm lattice spacing. After loading a Bose-Einstein condensate in the lattice potential we use…
