Abstract
Abstract
Absorption of a pulse of laser light in the surface region of a solid causes a fast temperature increase, followed, after the end of the laser pulse, by a rapid decrease to the base temperature. Experiments with a Nd laser (power 105 - 106 W/cm2, half width of the pulse 150 μsec) showed that desorption of CO from a Pd surface reaches its maximum rate within the time constant of the system ( ~ 0.5 msec). This effect can be used for example to investigate the kinetics of adsorption /desorption processes by means of relaxation methods.
