Spatial quadratic optical soliton formation has been stud ed extensively in the past and recently Li et al demonstrated quadratic spatio-temporal soliton formation in LiIO_3 using tilted pulses In this article we report self-focusing and intensity dependent walk-off compensation in LiIO_3 using tilted pulses. Tilted pulses are space time coupled pulses which allow control of dispersive propagation in normally dispersive materials. In this study we focus a short tilted pulse in the dimension transverse to the tilt and observe intensity dependent spatial shifts. We explore this intensity dependent spatial shift for thresholding and limiting application using ultrashort tilted pulses.
