Laguerre-Gaussian beam propagation calculator

Laguerre Gaussian beam propagation calculator

About the program

This program is a combination of two programs. The core program – main.exe was written by Raimondas Ciegis and Galina Silko. Raimondas Ciegis and Galina Silko has developed numerical algorithm to calculate beam propagation. Beam is described in Laguerre Gaussian modes. The physical problem was designed by Aleksandr Dementjev.

I developed an adapter to main.exe program. I call it LGcalculator. With this adapter you can run parametrized problems and get all spectra of solutions. I have also developed program LGanalyzer. With a help of LGanalyzer one can analyze data calculated by LGcalculator. More description about the program is on the way.
