Abstract
A high pressure transverse excitation type laser oscillator comprises a plane anode and a plurality of rod type cathodes to form glow discharge. Each cathode is covered with a cylindrical insulator having heat resistance except for a small discharge surface whereby the shift of the glow discharge caused by varying the pressure or the discharge current can be prevented to thus obtain stable glow discharge.
