Optical cavity misalignment
WebOptical cavities are widely used in the field of laser interferometry, and longitudinal length shifts of a cavity mirror and the resulting change in the phase of the resonating field are well known. WebWhen a parameter of a laser resonator (optical cavity) such as an arm length or the dioptric power (inverse focal length) of the focusing element in the resonator is varied, the resonator may go through one (for ring resonators) or two …
