Most such research so far has been demonstrated in bulk crystals.
Optical parametric generation (OPG) (also called "optical parametric fluorescence", or "spontaneous parametric down conversion") often precedes optical parametric amplification. In optical parametric generation, the input is one light beam of frequency ωp, and the output is two light beams of lower frequencies ωs and ωi, with the requirement ωp=ωs+ωi. These two lower-frequency beams are called the "signal" and "idler", respectively. WebBoth second harmonic generation (SHG) and tunable optical parametric generation (OPG) are described. Significantly greater efficiencies and/or lower thresholds are achieved with PPLN than are possible with conventional materials. Then, I will describe an entirely new nonlinear optical process.
