Study effect of using electric field and low pressure on laser drilling process
Engineering and Technology Journal,
2009, Volume 27, Issue 4, Pages 144-156
AbstractIn this work, the effect of electric field at low pressure (10-2m bar) on laser drilling
process has been studied for Stainless-Steel type (304) and brasses.
Nd: YAG pulsed laser (1.06μm) of (300μs) pulse duration at various energy ranges
between 0.5and 3J was used. The results indicated that the obtained maximum aspect
ratio for St. St. equals to (49%) at maximum used Energy. However the obtained
maximum aspect ratio for brass is (36.6%).
