Abstract
A gas laser in which the gas is excited by laser discharge, said laser including two capacitors formed by two parallel metal plates (2, 3) between which two dielectric parts (4,5) are spaced apart to form a passage (6) which contains the laser gas. It further includes a transformer (13) whose secondary winding (12) is connected to the plates and whose primary winding (14) is connected in series with a capacitor (15), means (17) for charging and capacitor and a thyristor (16) for discharging the capacitor in the primary winding. Application to exciting gas lasers in which the gas contains a dye stuff.
