Gaussian beam Dictionary Terms
Gaussian profile
An intensity distribution (intensity as a function of radial distance from the beam center) which is given by the Gaussian function: where: I0 is the intensity at the beam center r is the radial distance from the beam center ω0 is the radius...
absorbing wedge
A doped or absorbing transparent medium cut or molded into a wedge in order to measure the real and imaginary components of...
Gaussian optics
1. That branch of optics that illustrates the theory in which q is substituted for sin q in Snell's law. Effective results...
Gaussian beam
A beam of light whose electrical field amplitude distribution is Gaussian. When such a beam is circular in cross section,...
beam shaper
A beam shaper is an optical device or system designed to modify the spatial profile or intensity distribution of a laser or...
beam waist
That point in a Gaussian beam where the wavefront has a curvature of zero and the beam diameter is a minimum.
Rayleigh range
In the region of a Gaussian beam focus by a diffraction-limited lens, it is the axial distance from the point of minimum...
radially variable reflectivity optic
A reflecting optic whose reflectivity is a function of the radial distance from the optic axis; can be used to convert a...
