Anomalous diffraction of idler beam generated in optical parametric amplifier
Abstract
The diffraction of idler beam generated in optical parametric amplifier operating at low parametric gain is analysed. It is revealed that diffraction properties of idler beam under propagation in the free space is significantly different in comparison with the properties of Gaussian beam.Keywords: nonlinear optics, diffraction, optical parametric amplifier
