basic paraxial optics toolkit

by

 

01 Jul 2007 (Updated )

A set of paraxial optics functions for beam propagation and modal decomposition. Numerous examples.

File Information
Description

This toolkit has two main purposes.

1. Decomposition and visualization of paraxial beams in Hermite-Gaussian and Laguerre-Gaussian bases. (These functions are located in the subdirectory "transverse.")

2. Propagation of such beams through optical systems including two-mirror fabry-perot cavities. (These functions are located in the subdirectory "axial.")

There is a smattering of other stuff, including the representation of an apodized (clipped) Gaussian beam in terms of its asymptotic expansion (giving Airy patterns.)

All the functions have comments and headers that should enable interested persons to use them. There is also a set of examples demonstrating the basic capabilities.

MATLAB release MATLAB 7.2 (R2006a)

Great work!
I have problems plotting the LG beam intensity and phase when 'm' the orbital angular momentum goes to values 10-16 !?

does anybody know why the simulation doesnt work if you make the cavity length small in the range of a few centimeters?

the code doesnt crash but it doesnt plot anything..

There are some bugs in the routines. The demos do not work properly and the documentation is hard to follow.

I think it may be useful for me
Thank you very much for your uploading optical programs! I need them.
