Radius of curvature gaussian beam
WebIn fact, a Gaussian beam has the smallest possible (diffraction limited) BPP, which can be interpreted as the highest possible beam quality. During propagation in a homogenous medium, a Gaussian beam stays Gaussian, only its parameters (beam radius, wavefront curvature radius, etc.) change. The same holds for propagation through thin lenses or ... WebMathematically model beam propagation of Gaussian beam using simple geometric parameters.

Radius of curvature gaussian beam
Did you know?
Since the Gaussian beam model uses the paraxial approximation, it fails when wavefronts are tilted by more than about 30° from the axis of the beam. From the above expression for divergence, this means the Gaussian beam model is only accurate for beams with waists larger than about 2λ/π.
