Experimental results on the etching of SiC ceramics induced by a copper vapor laser in various environments (air, (CH3)2SO (DMSO), N2H4, H2O) are presented. Strongly non-equilibrium conditions of the etching process result in the decomposition of the

We experimentally studied the transmission of the Er3+:YAG laser radiation (λ = 2.94 ´m) by strongly absorbing liquids in the mode of free running. The radiation was shown to pass through liquids due to the development of a channel, produced by the
