Abstract
Radiation pressure on metastable helium atoms can be increased by an order of magnitude using the combined action of two lasers exciting the 1s2s S13- 1s2p P23- 1s3d D33 cascade. This increase has been measured as a function of laser intensities and is explained in a model based on the optical Bloch equations, the coherences playing a crucial role. Possible applications for deceleration are discussed. © 1995 The American Physical Society.
