Title: GAS LASER DEVICE
Abstract:
This gas laser device (1) is provided with: a gas laser tube (10) for generating laser light by exciting gas sealed in an internal space (12); and a window member (20) attached to one axial end side of the gas laser tube (10), wherein the window member (20) has a uniaxial-crystalline transmission region (22). The transmission region (22) is configured to allow laser light to be pass therethrough, and the window member (20) is attached to the gas laser tube (10) so that the optical axis of the laser light passing through the transmission region (22) and the optical axis of the uniaxial crystal are approximately parallel.
