Gaussian beam with a finite waist (focused beam).

Fields

origin: Vec3

direction: Vec3

waist: f32

wavelength: f32

Implementations

impl GaussianBeam

pub fn new(origin: Vec3, direction: Vec3, waist: f32, wavelength: f32) -> Self

pub fn rayleigh_range(&self) -> f32

Rayleigh range: z_R = pi * w0^2 / lambda

pub fn beam_radius(&self, z: f32) -> f32

Beam radius at distance z from waist: w(z) = w0 * sqrt(1 + (z/z_R)^2)

pub fn intensity_at(&self, pos: Vec3) -> f32

Evaluate the beam intensity profile at a point.

pub fn evaluate(&self, pos: Vec3, time: f32) -> f32

Evaluate the complex amplitude (scalar, real part) at a point and time.
