Fast switching of alkali atom dispensers using laser induced heating.

Griffin, P.F. and Weatherill, K.J. and Adams, C.S. (2005) 'Fast switching of alkali atom dispensers using laser induced heating.', Review of scientific instruments., 76 (9). 093102.

Abstract

We show that by using an intense laser source to locally heat an alkali atom dispenser, one can generate a high flux of atoms followed by fast recovery (<100 ms) of the background pressure when the laser is extinguished. For repeated heating pulses a switch-on time for the atomic flux of 200 ms is readily attainable. This technique is suited to ultracold atom experiments using simple ultrahigh vacuum (UHV) chambers. Laser-induced heating provides a fast repetition of the experimental cycle, which, combined with low atom loss due to background gas collisions, is particularly useful for experiments involving far-off resonance optical traps, where sufficient laser power (0.5–4 W) is readily available
