摘要: An electrical excitation circuit (10) for a gas laser. The includes charging (16), connected in series with pulse forming network (18) between power source (12) and the laser load (14). capacitor charged by thyratron (S1) transferring voltage to (18). Alternatively, upon firing of silicon controlled rectifier (SCR1) through saturable step-up transformer (XFMR1) which saturates inductor switch (S2) positioned respect so that, when on reaches predetermined level, saturation releases energy stored is biaised means an bias current can be adjusted that after fully charged, thereby controlling time application high preferably additional magnetic diode (L3) also biased current. discharges other saturates, doubling across (14) at discharge. minimizes prepulse during capacitor. Neither nor are discharge loop (LD) minimizing inductance (LD).
