A Facility for Studying the Spatial and Temporal Characteristics of a Plume Produced by Interaction of High-Power CO_2 Laser Pulses with a Solid-State Target in Various Gas Environments

摘要

An experimental facility for studying the kinetics of molecular association formation from atoms produced by evaporation of the target material by powerful CO_2 laser pulses is described. First experimental results are presented for the spectral and spatial - temporal characteristics of the spread of Al atoms produced in interactions of laser radiation with aluminum oxide Al_2O_3, followed by AlO formation in various low-pressure (0.1-0.3 Torr) atmospheres. Images of structurally similar forms condensed on a glass surface have been observed with an atomic-force microscope.
