PreciLaser. Laser driver for PreciLaser lasers. 🚀
SacherLion. Laser driver for Sacher Lion laser diode. 🚀
PyPrl PyRPL is an open-source software package and could be used to lock a laser.

Piezo. Python interface for Thorlabs piezo devices. 🚀
pylablib. Control different Thorlabs motorized devices: piezo, rotating mounts. (Windows only).
APT - lower level than kinesis, to control Thorlabs motorized devices. It works on Linux.

Control scope. Python interface for oscilloscopes communicating via SCPI commands through PyVisa. USB or TCPIP or anything. 🚀
Tenma power supply current and voltage. Code for controlling the Tenma 72-2715. 🚀
Arduino actuator. Arduino driven linear actuator. 🚀
PyPrl PyRPL is an open-source software package providing many instruments on cheap FPGA hardware boards.

LambdaMeter. A Python interface for HighFiness wavelengthmeters, with a server and client built-in to allow remote access. 🚀
LambdaMeterWeb. A Python + HTML + API interface with graphic webpage to have remote access to the HighFiness wavelengthmeters. 🚀

pyVISA. Python package to enable control of measurement devices independently of the interface.
pySerial. Encapsulate the access for the serial port.
pyUSB. Easy USB devices communication in Python.

Phase. Utilities to retrieve and process phase information of optical fields, live monitoring of the phase. 🚀

NLSE. Utility to simulate non linear Schrödinger equation (Split-step spectral scheme). 🚀
OBE. Solving Optical Bloch Equations. 🚀
Rubidium Spectrum Model. Python code to calculate absorption spectra for the Rb lines.
Transit. Transit effects for non-linear index measurement in hot atomic vapors. Both measurement utilities and numerical estimation. 🚀
Electric susceptibility - ElecSus. A program to calculate the electric susceptibility of an atomic ensemble. The program is designed to model weak-probe laser spectra on the D-lines of thermal alkali metal vapour cells. The program also includes fitting routines which allow experimental parameters to be extracted from experimental spectroscopic data.
MEEP. Open source FDTD software with a python interface to solve Maxwell equations in mateials and nanostructures (see an example for nanofiber optimization).
Tidy3D. An other FDTD software for electromagnetism simulation (not open source) with a nice web interface and very fast. Possibility to get a free educational licence.

Cupy. Open-source array library for GPU-accelerated computing with Python.
Numba. Open source JIT compiler that translates a subset of Python and NumPy code into fast machine code.
Cython. Optimising static compiler for both the Python and the extended Cython programming language (based on Pyrex).
Tensorflow. Create production-grade machine learning models.
FFT. Pythonic wrapper around FFTW, the speedy FFT library.

Gaussian Beam free software to calculate profile of gaussian beams through lenses (to calculate waist fx)

Use a gradient of color in your plot. See the example.
Use a slider - See the example with a discrete slider and parametric plots.
f-string formatting. Format strings of your plot (labels, titles...) with data. See the example.
Cycler. Personnalize the way matplotlib cycles through the colors of the colorbar. See the example.
Animation. Animate your plot (1D or 2D). See the example from PhaseUtils/monitor_phase.py.
