Abstract
An electrical discharge occurs between the anode and the cathode and the active gas such as CO.sub.2 between the two electrodes is excited to provide a laser beam. The laser beam thus provided is reflected repeatedly by a pair of reflection mirrors. The reflected laser beam is amplified while passing through the space where the discharge occurs, thus providing the function of a gas laser oscillator. Although the amplification that occurs in the discharge zone between the electrodes, considerable laser beam absorption takes place in the space between the reflection mirrors and the electrodes. In this space, the amount of operating gas such as CO.sub.2 is reduced, or the space is evacuated. Alternatively, the space is cooled by causing the gas therein to flow. A reduction in so-called laser beam absorption function is provided.
