摘要： A system for conversion or amplification using quasi-phase matched nonlinear optical wave-mixing is described. The system comprises a first radiation source for providing a pump radiation beam, a second radiation source for providing a signal radiation beam, and a bent structure for receiving the pump radiation beam and the signal radiation beam. The radiation propagation portion of the bent structure is made of a uniform three-dimensional material at least partly covered by a two-dimensional or quasi- two-dimensional material layer and the radiation propagation portion comprises a dimension taking into account the spatial variation of the nonlinear optical susceptibility along the radiation propagation portion as experienced by radiation travelling along the bent structure for obtaining quasi-phase matched nonlinear optical wave-mixing in the radiation propagation portion. The dimension thereby is substantially inverse proportional with the linear phase mismatch for the nonlinear optical process. The system also comprises an outcoupling radiation propagation portion for coupling out an idler radiation beam generated in the bent structure.

摘要： A frequency converter is configured from a phase-matched non-linear crystal portion which frequency-converts radiation of one or more input beams to the desired frequency of the signal beam. Due to birefringence of the phase-matched crystal portion, the input and signal beams propagate at a walk-off angle relative to one another along the entire length of the phase-matched portion. The frequency converter further includes a non-phase-matched non-linear crystal portion receiving the input and signal beams which continue to propagate at the walk-off angle so as to be spatially separated from one another at the desired distance after exiting the output of the non- phased portion. The desired distance is selected to provide unobstructed propagation of the signal beam to the target to be irradiated while the input beam(s) is incident on an optical component preventing the input beam from impinging upon the target.
