Optics
Laser Beam Parameters Calculator
Compute key Gaussian laser beam properties — Rayleigh range, half-angle divergence, or beam radius at any distance from the waist. Essential for laser system design, focusing optics, and beam alignment tasks.

Optics
Laser Beam Divergence Calculator
Calculate how a laser beam's spot radius grows with propagation distance, accounting for beam quality factor M². Use this when designing laser systems, targeting applications, or evaluating beam collimation quality.
