ABSTRACT:
An electro-optic deflector51has an electro-optic material body519through which an optical beam46is passed. The deflector has no more than three longitudinal electrodes, of which no more than two electrodes511, 512have arcuate transverse cross-sections. The electrodes are arranged to create an electric field substantially transverse to a direction of the optical beam to deflect the optical beam passing between the electrodes. The electro-optic deflector has particular application in a Q-switched laser for generating sub-nanosecond optical pulses.
