About this Simulation

This simulation models laser pumping—the process of exciting electrons to higher energy levels using photons. Learners can observe how atoms absorb light energy, transition between quantum states, and release energy through stimulated emission. Adjust parameters like photon frequency and observation range to investigate the quantum behaviour underlying laser operation.

Learning objectives: Understand energy level transitions and photon-atom interactions | Visualise how laser pumping excites electrons in quantum systems | Explore the relationship between photon frequency and electron energy transitions
