Energy-efficient conditions of glass and ceramic materials laser processing

Within the framework of the one-dimensional problem of the evaporation of an absorbing material layer at For the release of laser pulse energy, analytical relationships are obtained for calculating the required energy density at a given scribing depth. These ratios make it possible to determine energy-saving modes of scribing glassy and ceramic materials with volumetric absorption of laser radiation when exposed to one or two laser pulses. The choice of the processing mode depending on the dimensionless parameter [chi; h] makes it possible to reduce energy consumption by a maximum of 25 - 35%.
