Reconfigurable focusing of nonlinear signals via wavefront shaping method based on SM. (a) Measured SM which connects the input modes (horizontal axis) and output nonlinear modes (vertical axis). Hue and brightness represent phase and amplitude, respectively. Calculated phase patterns (b) and the corresponding focal spots (c) located on different positions of ROI. (d) Intensity cross-section of the nonlinear focal spots located on different sub-regions of ROI.
