physicsbox

Collection of useful calculations for optics and more. Intended to be a little toolbox/swiss army knife for everyday Python tasks for physists.

Requirements

• numpy
• scipy
• (optional) numba to speed up OAP calculations

Installation

Since the package is still under development, I recommend to clone this git repository to your local machine and install the package in "develop" mode via pip.

• git clone https://gitlab.lrz.de/cala-public/packages/physicsbox.git
• cd physicsbox
• pip install -e . where the -e installs in develop mode and . executes the setup.py in the current folder

If you make improvements to the package or want to download more recent commits, you can now just use git push/pull as usual.

Features

So far, the package contains the following submodules:

• .units which defines constants like m=1, mm=1e-3 and so on to use in your code
• .utils contains some coordinate system handling that can be used to plot e.g. an image to scale easily
• .optics for
  • laser pulse calculations (power, energy, focus size etc. by typical formulas)
  • Gaussian pulse (in time and space) function definitions for 1d, 2d, 3d Gauss calculations
• .relativity is pretty basic so far, only contains a few formulas for relativistic energy/momentum etc.
• .wavefronts contains classes for reconstructing a wavefront from Shack-Hartmann images (see examples for use)
• .oap contains a class for vectorial calculation of the focus of an off-axis parabolic mirror
• Check out the examples for some things that this package is intended for.

Contributing

• This started out as a private little helper project, if you have any suggestions just contact me.
• If you wish to make improvements or add new examples/ features, best create a new branch and a merge request.
  • This avoids headaches just in case I have uncommited/unpublished changes in my local copy somewhere.
