To provide a laser oscillator capable of suppressing a cost when providing a case body with a viewing window.
The laser oscillator for which a laser medium is enclosed inside the case body with a discharge electrode and an optical resonator structure is provided in a direction orthogonal to a discharge direction is provided with: the viewing window 15 covering an opening formed at the prescribed position of the case body and having a step structure so as to fill a space surrounded by the opening; an O ring 22 held between the viewing window 15 and the case body for sealing the inside and outside of the case body; a window presser 24 for holding the peripheral edge part of the viewing window 15; and a fixing bolt 25 for fixing the window presser 24 and the case body.
