a combination of pre ionization, including pre irradiation by x-rays, and discharge gas laser pumped by excimer lasers, in particular, is connected to a pulse generator circuit for a gas laser system.a pulse transformer (pt) of the high voltage is connected to a primary winding (w1) of a storage capacitor (c1) and a high voltage switch (s) in the system pulse generator.the pulse transformer (pt) transmits pulse pre ionization as a combination of pre ionization (ve), including an x-ray tube (rr), the leading to the outbreak of the discharge pulse of laser light. to this end, the pulse transformer (pt) is a saturable magnetic inductor with at least one secondary winding (w2).when the high voltage switch (s) is closed, the primary winding of the pulse transformer (pt) reached its maximum inductivitu00e9 saturated, in order to generate, at that time, in accordance with the law of induction, a secondary pulse voltage.after a predetermined time of 50 to 100 ns, for example, the core is saturated, the inductivitu00e9 (lp) of the primary winding current decreases rapidly, and the flow in the circuit of inversion, resulting in the accumulation of the high voltage at the level of the us in its entirety some of the laser (e1, e2), which triggers the discharge.
