Optical finesse
WebNov 4, 2014 · Optical resonators are widely used in photonics, for example as a wavelength locker, a sawtooth-spectrum generator, or a displacement-measuring tool. One of the most important qualities of an optical resonator is its finesse F. (To understand F intuitively, consider that the spectral transmission of a Fabry–Perot resonator consists of an evenly … WebAn optical etalon (also called Fabry–Pérot etalon) was originally a Fabry–Pérot interferometer in the form of a transparent plate (often made of fused silica) with parallel reflecting surfaces ( solid etalon ). However, the term is often also used for Fabry–Pérots consisting of two mirrors with some air gap in between ( air-spaced etalon ).
