Abstract

A device capable of drastically improving the energy efficiency of present mask based laser materials processing systems is presented. Good accordance between experiments and simulations for a TEA-carbon-dioxide laser system designed for laser marking has been demonstrated. The energy efficiency may be improved with a factor of 2 - 4 for typical mask transmittances between 10 - 40%.
