A stochastic rainbow caustic observed with cold atoms
B. T. Wolschrijn, D. Voigt, R. Jansen +4
We report the direct observation of a novel type of rainbow caustic. In contrast to known examples, this caustic originates from a dissipative, stochastic process. We have observed…

Elastic and Inelastic Evanescent-Wave Mirrors for Cold Atoms
D. Voigt, B. T. Wolschrijn, R. A. Cornelussen +4
We report on experiments on an evanescent-wave mirror for cold Rb atoms. Measurements of the bouncing fraction show the importance of the Van der Waals attraction to the sur…

Characterization of a high-power tapered semiconductor amplifier system
D. Voigt, E. C. Schilder, R. J. C. Spreeuw +1
We have characterized a semiconductor amplifier laser system which provides up to 200mW output after a single-mode optical fiber at 780nm wavelength. The system is based on a taper…
