LIAD effect

LIAD - introduction

The Light Induced Atomic Desorption effect (LIAD), discovered by A. Gozzini et al. [1], is observed whenever pyrex cell, coated with thin siloxane film and containing alkali atoms is illuminated. LIAD is a nonthermal effect and has no relation with those desorption phenomena driven by powerful laser pulses, which produce a brute local heating of the substrate and surface ablation.
