Abstract
A laser oscillating apparatus has a compact, simple structure by utilizing the laser housing itself as an optical bench. Means for thermal expansion and contraction in the longitudinal direction of the laser housing are supported in the laser housing as a united body. The blower which circulates the lasing gases is constructed of a plurality of fans mounted for separate thermal expansion and contraction, enabling the use of high speed fans. Means are provided between the blower and the lasing region for cooling and smoothing the gas flow. The cap of the laser apparatus is arranged at the strength center of the housing to ensure a gas-tight interior.
