ABSTRACT:
A gas laser oscillator has two discharge tube columns, both ends of which are connected by a bending unit, wherein each column comprises two discharge tubes connected in series. At the opposite ends of the bending unit, one column has a total-reflection mirror, and the other column has a partial-reflection mirror. These discharge tubes, the bending unit, the total-reflection mirror, and the partial-reflection mirror are mounted to a single optical bench. Each end of the discharge tubes is fixed to the optical bench by a clamp. When counted from the clamp nearest to the partial-reflection mirror, the first clamp, the fourth clamp, and the eighth clamp are non-movable with respect to the optical bench, while the remaining clamps are movable, and thus adjustable. One total-reflection mirror unit of the two total-reflection mirror units on the bending unit is non-movable, and the other total-reflection mirror unit is movable.
