Bichromatic Slowing and Collimation to Make an Intense Helium Beam
Abstract
The bichromatic force has been used to both slow and collimate a beam of metastable 23S He atoms (He*). The collimation capture range is an extraordinary ±85 m/s corresponding to ∼0.18 radians from our source. Both slowing and collimation were accomplished in the unprecedented short distance of ∼5 cm each. The overall brightness increase is ×3200, and there is potential for considerably more.
