Abstract
An argon (Ar.sup.+) laser has a resonator. A reaction chamber is integrally formed in the resonator. A voltage is applied to electrodes, which discharge electricity to excite argon atoms in the resonator to produce a laser beam. The laser beam is continuously oscillated between total reflection mirrors disposed at opposite ends of the resonator. A substrate is disposed in the reaction chamber into which a material gas is introduced. The material gas absorbs the laser beam, to decompose and deposit as a thin film over the substrate.
