The Round-trip Phase Shift in an Optical Resonator

Web• The phase shift imparted by a round trip is. P.

P. Piot, PHYS 630 ... The spectral response of a Fabry–Pérot resonator is based on interference between the light launched into it and the light circulating in the resonator. Constructive interference occurs if the two beams are in phase, leading to resonant enhancement of light inside the resonator. If the two beams are out of phase, only a small portion of the launched light is stored inside the resonator. … hearth decorating tips
