Obtaining Fractals in a Fabry-Perot Interferometer

Fractals, 1997
The aim of this paper is to prove that, with a reflection coefficient of R<2-1/2, the series expressing the amplitude of the light beam transmitted by a Fabry-Perot interferometer, can be a fractal series. It is assumed as a starting point that the incident beam is maintained for an indefinite time and that its amplitude is constant.

Fabry-Perot interferometers with three mirrors

Applied Optics, 1986
The properties of two-mirror Fabry-Perot interferometers can be improved by adding one or more partially reflecting mirrors. In this paper we show how three-mirror Fabry-Perot interferometers provide better control on the shape of the transmission band, the bandwidth, and the suppression of sidebands. We present measurements on three-mirror Fabry-Perot

Intensity transmitted by a Fabry-Perot etalon with another internal Fabry-Perot interferometer

Applied Optics, 1981
The intensity transmitted by a device made up of a F.P. etalon that contains another internal tunable F.P. has been studied. The theoretical predictions about the wavelengths of the intensity transmission maxima of the device are derived as functions of the optical path length of the internal F.P. An experimental check of the theoretical predictions is

The Spherical Mirror Fabry-Perot Interferometer

Applied Optics, 1968
The theory, design, and use of the confocal spherical mirror Fabry-Perot interferometer (FPS) is described in detail. Topics covered include performance of an FPS for small departures from the confocal mirror separation, optimization of the (resolution) x (light gathering power) product, factors limiting realizable finesse, mode matching considerations,

Fringe broadening in Fabry-Perot interferometers

Applied Optics, 1984
Simple expressions are given for the halfwidth and finesse of a Fabry-Perot interferometer fringe broadened by defects. The expressions are unrestricted as to defect magnitude and have good accuracy for most practical forms of defect. The results are applicable to mirror surface defects, parallelism errors, angular dispersion of illumination, finite ...

Recording Fabry-Perot Interferometer

Review of Scientific Instruments, 1968
A recording interferometer is described in which a direct plot of spectral intensity against wavenumber is obtained without the use of a time base. When used as a double recorder, the instrument records two spectral profiles simultaneously. In this form, the recorder is particularly suited to the comparison of spectral profiles and the measurement of ...

A Fabry-Perot interferometer for atoms

Optical Society of America Annual Meeting, 1992
Recent progress in atom optics has culminated in several demonstrations of atom interferometers. These rely on the passage of atoms through mechanical or light gratings and may be roughly characterized as Mach–Zehnder interferometers. In this communication, we propose a scheme to realize a Fabry–Perot interferometer for atoms.

Microcomputer stabilization of a Fabry-Perot interferometer

Review of Scientific Instruments, 1978
Fabry-Perot interferometers typically require some form of active stabilization system for long-term operation. A stabilization system based on a microcomputer is described which is able to maintain the finesse of a plane parallel Fabry-Perot interferometer for long periods of time.
