Analysis of Variants of Pulsed Laser Punching of Through Holes in Glassy and Ceramic Plates

Abstract

Analytical relations for calculating the energy density required to punch through holes in nonmetallic plates are obtained in a one-dimensional formulation of the problem of evaporation of an absorbing layer of matter accompanying instantaneous energy deposition by a laser pulse for three variants of laser action as well as for calculating the mass of matter evaporated per unit energy deposited. A comparative analysis is made of the variants of the laser action on a plate, showing that the energy expended in punching through holes in glassy and ceramic plates can be reduced.
