Abstract
Huge light-induced rubidium atom desorption has been observedfrom porous silica samples placed inside Pyrex cells kept at roomtemperature. The desorption rate and the maximum vapour densitychange have been measured as a function of the desorbing lightintensity. Their values are comparable with those recentlyobtained in Pyrex cells coated with organic films. A lineardependence of the desorption rate and a square-root dependence ofthe maximum density increase on light intensity indicate thatdiffusion inside the glass pores is a key mechanism. Theapplication of this effect to develop light-controlled atomicdispensers compatible with high vacuum environment is discussed.
