Abstract

The threshold modes of metal cutting by combined radiation of CO₂ laser with a ring TEM₀₁ mode, 800 W power, 200 microns beam diameter and pulse-periodic Nd:YAG laser with a TEM₀₀ mode, 90 microns beam diameter, 80 W average power are investigated. It was established, that improvement of CO₂ laser radiation usage efficiency and narrowing of the cutting channel to Nd:YAG laser spot diameter is caused by tightening of radiation into the narrow channel.
