IterMODE
Software for designing diffractive optical elements (DOEs) to generate Gauss-Laguerre, Gauss-Hermite and Bessel modes (using algorithms for approximating the complex function by a finite number of basis functions).

Developed: LLM. Adopted at the FIAT Research Center.

The PC display in the process of analysis of modal composition
of a multi-mode Gauss-Laguerre beam

1. Parameters' window: of light beam composition and filter, initial phase type, iterative technique, number of iteration, ...
2. Amplitude radial section.
3. Protocol window: input parameters and efficiency in the course of iteration.
4. 3-mode light beam.
5. Table of modal composition of spatial filter.
6. Phase photomask 9-mode spatial filter.
7. Filter's effect: intensity peaks at points corresponding to the modal composition of the illuminating beam (2D and 3D patterns).
