Abstract
A metal vapor laser apparatus has a gas supply device. The device supplies at least two kinds of gases to a container of the laser apparatus controlled individually. One of the gases is selected from the group of the molecular gas such as hydrogen gas, the other is selected from the group of rare gas such as neon gas. By adjusting the mixture ratio of these gases, the laser beam output is obtained efficiently. The molecular gas should be supplied when a metal lump, such as copper, arranged in the container is melting.
