Relatively new branch of opto-mechanics explores emergent nonlinear effects, directly related, or mediated by mechanical motion of particles on nano-scale. Nonlinear phenomena are starting to kick in once traditional CW trapping sources are replaced by impulse illumination. Under certain circumstances, utilization of short pulses enable achieving lower trapping powers and mitigates heating effects. On the other hand, high peak intensity gives rice to effects of nonlinear generation. Furthermore, traditional system with a single trap could exhibit 2 trapping centres once short pulses are used instead of CW. Optical attractors, based on vortex solitons could be also achieved. At the moment, the area of nonlinear opto-mechanics just started to develop, but already holds a great promise for delivering fundamental breakthroughs and applications.
