Beschreibung
Zusammenfassung:	A high speed light beam modulator includes an electro-optic modulator which is connected in series with an inductor to form a series resonant circuit. Switching means selectively allows current to flow in the inductor for a predetermined period. The switching means then interrupts the flow of current, causing oscillations in the series resonant circuit. The oscillations are damped after the first half cycle of voltage oscillation appearing across the electro-optic modulator.
