ABSTRACT:
A method of irradiating a metal piece (5) with a laser beam for generating a metal vapor (11) required for a metal vapor laser to oscillate. The method makes it possible to reduce the time required to activate the laser as well as the response time required to adjust the metal vapor density. Metals having a high melting point can also be vaporized for laser oscillation in accordance with the method.
