Paper Abstract

The laser with power tens of kilowatt would be essential for dismantlement of obsolete nuclear-power reactors, laser-hardening the surfaces of railway rails and etc. The production of high power, high efficiency, high specific energy and high optical beam quality can be obtained in the experimental systems of a quasi-cw electroionization CO laser with cooling a CO mixture by its expansion in the nozzles. The way of transfer to industrial high-power CO lasers is proposed through the continuous formation of a CO laser mixture during laser operation. CO laser mixture is formed by using air as a buffer gas (about 90%). CO molecules are generated in oxidation reaction of oxygen-containing molecules with carbon. The carbon arises from a decomposition of hydrocarbon fuel on the catalyst surface. CO mixture is excited by radio-frequency (RF) electric discharge in a supersonic gas flow without an electron gun. The given conception was used on a small-scale model system to demonstrate that the laser radiation was possible in a CO mixture with combustion products and air, which are excited by RF discharge in a supersonic flow. The industrial CO laser with tens of kilowatt power is offer with open working cycle without ejecting toxic CO into the atmosphere by converting CO molecules to C02 ones. The estimated cost of a laser is several hundred thousand and the small sizes of laser give possibility to install its on manipulator without fiber-optic delivery.
