Electro-optical modulator for an electro-optically modulated laser
This patent describes an electro-optically modulated laser, comprising a lasing medium, a pair of spaced etalons and a birefringent electro-optical device arranged in an optical cavity. The improved electro-optical modulator includes: a hydrogen thyratron having an ''ON'' and an ''OFF'' state; means for selectively pressurizing the hydrogen thyratron; means, response to the ''OFF'' state of the hydrogen thyratron, for impressing a first preselected voltage across the birefringent electro-optical device; means, responsive to the ''ON'' state of the hydrogen thyratron, for impressing a second preselected voltage across the birefringent electro-optical device in a time that corresponds to the laser buildup interval; and means for repetitively driving the hydrogen thyratron into the ''ON'' and the ''OFF'' states.
