About this Simulation

This interactive simulation models the TEM00 (Transverse Electromagnetic) mode of a laser beam using contour plot visualisation. Learners explore how beam intensity varies spatially, adjust beam parameters like waist radius and power, and observe the resulting intensity distribution patterns in real-time. Perfect for understanding fundamental laser beam characteristics.

Learning objectives: Understand the spatial intensity profile of the fundamental TEM00 laser mode | Relate beam waist, power, and intensity parameters to visualised contour patterns | Apply Gaussian beam theory to predict and explain laser beam behaviour
