Nonlinear optical effects
Two-dimensional degenerate mixing of two waves in a nonlinear medium
A. N. Bobrovskiĭ, E. B. Levchenko, G. D. Myl'nikov
Abstract:
An analysis is made of the interaction of two coherent waves of different intensities in a thin layer of a transparent nonlinear medium. It is shown that such interaction or mixing can amplify the weaker wave without altering its wave front. A report is given of an experimental demonstration on the amplification of a spherical CO2 laser radiation wave by interaction with a high-power spherical wave (with a different radius of curvature) in a thin layer of gaseous SF6. The applications of this effect in correction of wave fronts and enhancement of the intensity in phase images are considered.
