We present the experimental realization of a compressible blue detuned crossed dipole trap for cold atoms allowing for fast dynamical compression (~ 5 - 10 ms) of 5x10^7 Rubidium atoms up to densities of ~ 10^13 cm^-3. The dipole trap consists of two intersecting tubes of blue-detuned laser light. These tubes are formed using a single, rapidly rotating laser beam which, for sufficiently fast rotation frequencies, can be accurately described by a quasi-static potential. The atomic cloud is…

Simple and effective coupling technique for polarization maintaining fibers.

A simple and effective technique for coupling free-space laser beams into polarization maintaining fibers (PMFs) with high coupling efficiency and it is demonstrated that theoretical maximum coupling efficiency can be approached by using a mode-filtered beam.
