This is a program that provides a graphical solution for the population inversion of the levels 2 and 3 of the Argon laser atomic system.

Provided program was created in Python3 IDLE using numpy, scipy and mathplotlib libraries.

Argon laser has a 4-level atomic system where the transition of the atoms between levels 2 and 3 is important for receiving the emission in blue and green regions of the electromagnetic spectrum (488 nm and 514.5 nm).

My program calculates system of the 4 coupled differentian equations using odeint library and matplotlib library to visualise the result.

-Make sure you have Pyhton3 IDLE.

-Download Population Inversion for Ar Laser Atomic System.py file.

-Run the Population Inversion for Ar Laser Atomic System.py file with the following packages installed:

• math
• numpy
• scipy
• mathplotlib
