Briefing: Beam Reconstruction By Iteration Of An Electromagnetic Field With An Induced Nonlinearity Gauge
Abbreviated Journal Title
Measurement of the local intensity and phase distributions in the small focal waist of a laser beam with the use of a thin nonlinear-optical layer is discussed. We suggested and tested in a computer experiment the beam reconstruction by iteration of an electromagnetic field with an induced nonlinear gauge (BRIEFING) algorithm, which allows one to extract the absolute intensity (in watts per square centimeter) and phase distributions from two intensity patterns in the far-field zone: with and without nonlinearity.
