LASER DESORPTION: THE THERMAL APPROACH.

Research output: Contribution to journalConference articlepeer-review

Abstract

The time-dependent temperature behavior of a surface exposed to a high power, short-pulsed laser beam has been described by J. F. Ready and P. G. Kistemaker et. al. If one assumes that there is some 'activation energy' for desorption, then ions (or neutrals) will have a rate of desorption (integrated over the irradiated surface area). On the time-of-flight mass spectrometer, variation of the delay time between the laser pulse and an ion extraction pulse, provides a unique opportunity to observe the time-dependent desorption of different ions.
