WebIn optics, a Fabry–Pérot interferometer (FPI) or etalon is an optical cavity made from two parallel reflecting surfaces (i.e.: thin mirrors). Optical waves can pass through the optical cavity only when they are in resonance with it. It is named after Charles Fabry and Alfred Perot, who developed the instrument in 1899. Etalon is from the French étalon, meaning … WebThe optical cavity has a stronger effect on the gain of a FEL than in most conventional lasers and the gain can also affect the optical mode. The gain is maximized for an optimal overlap between the electron beam and the optical mode. As noted in Sec. 1.2 the electron beam acts as a spatial filter and typically produces a diffraction-limited ... laminate locking cabinet
