Microanalysis and Spectrophotometry

When the light from a pulsed laser is focused onto a solid surface, electrons 292 a) jgns, and neutral particles are evaporated 293-295) when the laser intensity exceeds a threshold value. Kinetic energy, temperature, degree of ionization and total mass of the expanding vapor cloud depend on incident laser power and pulse duration 296.297) 

A survey of the applications of lasers in micro- and macro-spectral analysis has been given by Gbrlich and Moenke-Blankenburgi 302) Their group in Jena has developed the technique of laser microprobing into a reliable and versatile tool for chemical analysis 302a).
