In this work, the effect of electric field at low pressure (10-2m bar) on laser drillingprocess has been studied for Stainless-Steel type (304) and brasses.Nd: YAG pulsed laser (1.06μm) of (300μs) pulse duration at various energy rangesbetween 0.5and 3J was used. The results indicated that the obtained maximum aspectratio for St. St. equals to (49%) at maximum used Energy. However the obtainedmaximum aspect ratio for brass is (36.6%).
