Shape-preserving diffusion of a high-order mode
The close relation between the processes of paraxial diffraction and coherent
diffusion is reflected in the similarity between their shape-preserving
solutions, notably the Gaussian modes. Differences between these solutions
enter only for high-order modes. Here we experimentally study the behavior of
shape-preserving high-order modes of coherent diffusion, known as 'elegant'
modes, and contrast them with the non-shape-preserving evolution of the
corresponding 'standard' modes of optical diffraction. Diffusion of the light
field is obtained by mapping it onto the atomic coherence field of a diffusing
vapor in a storage-of-light setup. The growth of the elegant mode fits well the
theoretical expectations
Modification of codes NUALGAM and BREMRAD. Volume 3: Statistical considerations of the Monte Carlo method
The statistics are considered of the Monte Carlo method relative to the interpretation of the NUGAM2 and NUGAM3 computer code results. A numerical experiment using the NUGAM2 code is presented and the results are statistically interpreted
