DEFLECTION OF A VELOCITY COMPRESSED YB ATOMIC-BEAM BY A MULTIMODE SPECTRAL LASER

We have generated a continuous, monovelocity Yb atomic beam based on a technique combining velocity compression and beam deflection. Two sin gle-mode lasers were used to compress the thermally broadened velocity distribution, and a multi-mode spectrum of a mode-locked laser was us ed to extract the compressed part as a deflected beam. The observed de flection angles were compared with the calculations. Deflection angles up to 12 degrees were obtained.
