About this Simulation

This simulation models the knife-edge technique for measuring laser beam profiles. Learners can adjust parameters including beam waist size, measurement distance, and knife-edge position to observe how intensity changes across the beam cross-section and understand Gaussian beam propagation characteristics in practical laser measurement scenarios.

Learning objectives: Understand how the knife-edge method quantifies laser beam profiles and Gaussian beam properties | Explore the relationship between beam parameters (waist, wavelength, distance) and intensity distribution | Apply measurement techniques to characterize real laser systems
