Intensity Dependence of Laser-Induced Emission of Particles from CaF2(111) near the Plasma Threshold

Desorption Induced by Electronic Transitions DIET IV

Part of the book series: Springer Series in Surface Sciences ((SSSUR,volume 19))

Abstract

Laser stimulated emission of electrons, ions and neutrals from CaF2(111) surfaces in UHV was studied around the breakdown threshold by time-of-flight techniques in UHV for 532 nm and 355 nm. The experiments were carried out with crystals cleaved in vacuum and heated to 3 00 °C. It is shown that the laser light is absorbed by the crystal via inverse bremsstrahlung/avalanche ionization. The intensity dependence of the particle and photon emission reflects the gradual transition from desorption of individual particles to plasma formation.
