Abstract
An electro-optic deflector 51 has an electro-optic material body 519 through which an optical beam 46 is passed. The deflector has no more than three longitudinal electrodes, of which no more than two electrodes 511, 512 have 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.
Claims19
An electro-optic deflector comprising an electro-optic material for passing an optical beam therethrough and no more than three longitudinal electrodes, comprising one of:
- two mutually inclined planar electrodes;
- and one or two electrodes with arcuate transverse cross-sections, arranged to create an electric field gradient substantially transverse to a direction of the optical beam to deflect the optical beam passing between the electrodes.
