KnowraCoherence lengthLinked fromLinked fromThe 9 pages that link to Coherence length, each with the reason it gives.All 9Related 9Michelson interferometerRelated: The arms must differ by less than the source’s coherence length for clear fringes.Diffraction gratingRelated: Coherence affects how sharply light from many grating periods forms interference maxima.Fabry–Pérot interferometerRelated: The source’s coherence must be sufficient for repeated cavity beams to interfere.Ginzburg–Landau theoryRelated: In this theory it sets the scale over which the order parameter recovers near a disturbance.Laser rangefinderRelated: Phase-based ranging depends on stable optical phase over the measurement path.Type-II superconductorRelated: It sets the vortex-core scale and helps determine the superconductor's type.Newton's ringsRelated: Sufficient coherence lets the two reflected waves form visible fringes.Abrikosov vortexRelated: It sets the approximate radius of a vortex’s nonsuperconducting core.Second-harmonic generationRelated: It sets the scale over which newly generated harmonic fields add constructively.
