Abstract

By using dispersionless nonlinear refraction in CS2, a weak 0.53 μm beam is deflected by up to 3 mrad by an intense, copropagating. 1.06 μm pump beam with an asymmetric transverse intensity profile. With a 100 ps pump pulse, the inferred scan rate of the visible beam is ≈108 rad/s, corresponding to ≈1011 defl. spots/s. Such ultrafast angular deflection may be applied to the generation of ultrashort optical pulses.
