Abstract
A thermal lensing material deflects a signal laser beam in accordance with he changing intensity of a contol beam. The intensity of the control laser beam creates a thermal lense effect to vary the refractive index of the crystal to responsively displace the signal laser beam. The relative orientations of the beams to the crystal and the degree to which the two laser beams are parallel to the optic axis also may be introduced as variables to effect the degree of displacement of the signal laser beam.
