Abstract

Smoothing of ablation pressure profile by controlling the position of the critical surface was explored using a double pulse regime for plasma formation. In the experiment performed on the PERUN single beam iodine laser facility ((lambda) equals 1.315 micrometer, E equals 40 - 50 J, conversion to blue approximately 50%) variations of the distance between the critical and ablation surfaces are achieved by changing the time delay and intensity ratio of the heating blue (third harmonic) irradiation of the Al-target through a preformed red (second harmonic) plasma.
