Abstract

Low-intensity white light was used to increase the loading rate of 87Rb atoms into a vapor-cell magnetooptic trap by inducing nonthermal desorption of Rb atoms from the stainless-steel walls of the vapor cell. An increased Rb partial pressure reached a new equilibrium value in fewer than 10 s after switching on the broadband light source. After the source was turned off, the partial pressure returned to its previous value in 1/e times as short as 10 s.
