Gaussian beams are used in optical and microwave systems.
It is typically formed by diffractive optical elements from a Gaussian beam.
Illumination was also much more uniform and produced fewer image artifacts than the conventional Gaussian beam.
The matrix formalism is also useful to describe Gaussian beams.
The 1/e width is important in the mathematics of Gaussian beams.
The M for a Gaussian beam is one.
Gaussian beams are just one possible solution to the paraxial wave equation.
For a Gaussian beam, no simple upper integration limits exist because it theoretically extends to infinity.
The basic, or fundamental transverse mode of a resonator is a Gaussian beam.
The two lenses act as a telescope producing a flat phase front of a Gaussian beam on a virtual end mirror.
