N2 - 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 5×107 rubidium atoms up to densities of ∼1013cm -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 quasistatic potential. The atomic cloud is compressed by dynamically reducing the trap volume, leading to densities close to the Ioffe-Regel criterion for light localization.
