In physics, coherence length is the propagation distance over which a coherent wave (e.g. an electromagnetic wave) maintains a specified degree of coherence. Wave interference is strong when the paths taken by all of the interfering waves differ by less than the coherence length. A wave with a longer … See more In radio-band systems, the coherence length is approximated by $${\displaystyle L={\frac {c}{\,n\,\mathrm {\Delta } f\,}}\approx {\frac {\lambda ^{2}}{\,n\,\mathrm {\Delta } \lambda \,}}~,}$$ See more • Physics portal • Coherence time • Superconducting coherence length • Spatial coherence See more Multimode helium–neon lasers have a typical coherence length on the order of centimeters, while the coherence length of longitudinally single … See more Tolansky's An introduction to Interferometry has a chapter on sources which quotes a line width of around 0.052 angstroms for each of the Sodium D lines in an uncooled low-pressure sodium lamp, corresponding to a coherence length of around 67 mm for … See more WebCoherence Length: Used in holography, interferometry: Long coherence length (~20-30cm) Short coherence length (a few millimeters) Polarization: Important if optical path is …
WebApr 11, 2024 · Abstract. The statistics of work done on a quantum system can be quantified by the two-point measurement scheme. We show how the Shannon entropy of the work distribution admits a general upper bound depending on the initial diagonal entropy, and a purely quantum term associated to the relative entropy of coherence.
