Non-phasematched Sum Frequency Generation from Tightly Focused High Gain Parametric Down Conversion

Non-phasematched Sum Frequency Generation from Tightly Focused High Gain Parametric Down Conversion

we study the sum frequency generation from high gain parametric down conversion with broadband spectrum in the absence of the phase matching. In the case of strong focusing, a set of interference spectral peaks in the spectrum of the second harmonic appear without the phase matching. Experimental da...

Description
Summary:we study the sum frequency generation from high gain parametric down conversion with broadband spectrum in the absence of the phase matching. In the case of strong focusing, a set of interference spectral peaks in the spectrum of the second harmonic appear without the phase matching. Experimental data supported by theoretical modeling reveal the influence of correlation effects on non-phase matched sum frequency generation.
