REGENERATION OF GAS FOR LASER IN CARBON DIOXIDE GAS LASER APPARATUS

摘要

PURPOSE:To provide an industrially practical technique in a carbon dioxide gas laser apparatus using a gas regenerator. CONSTITUTION:A gas flow path of a gas regenerator B in which a gas heater 5 and a catalyst bed 6 for gas regeneration are installed is connected to a gas circulating path of a laser generator A through a coupling. A catalyst is activated by circulating an activation gas or the gas caused by an activation is purged by a mixed gas for laser. Also, the gas regenerator B may have a gas circulating path in which a gas circulating fan and an adsorbent floor are installed.
