Abstract

A Q-switched ruby laser, focussed by means of both gas and glass lenses, was used to irradiate massive planar carbon targets. Two different laser configurations were used, giving differing spatial beam qualities. Faraday cups positioned at various angles about the target were used to monitor ion flow properties of the resulting laser-produced plasmas. These flow properties were used to compare the laser-plasma producing characteristics of the lenses.
