Journal ArticleDOI
Tunable Passively $Q$ -switched Erbium-Doped Fiber Laser With Carbon Nanotubes as a Saturable Absorber
TL;DR: In this paper, an all-fiber tunable passively Q-switched erbium-doped fiber (EDF) laser is presented, where saturable absorbers are constructed by optically driven deposition of single-wall carbon nanotubes on fiber connectors.
Journal ArticleDOI
Simultaneous measurement for strain and temperature using fiber Bragg gratings and multimode fibers
TL;DR: An all-fiber sensor capable of simultaneous measurement of temperature and strain is newly presented, and can be used to improve the strain and temperature resolution by suitably choosing the multimode fiber.
Journal ArticleDOI
Energies and widths of quasibound levels (orbiting resonances) for spherical potentials
Robert J. Le Roy,Wing-Ki Liu +1 more
TL;DR: A derivation for the previously proposed Airy function boundary condition method is presented, and a Weber function boundary conditions method for locating resonances which lie above the potential barrier maximum is derived, tested, and found wanting as mentioned in this paper.
Journal ArticleDOI
On the theory of the relaxation matrix and its application to microwave transient phenomena
Wing-Ki Liu,Rudolph A. Marcus +1 more
TL;DR: In this article, the phenomenological relaxation times T1 and T2 measured in microwave transient experiments are expressed in terms of specific molecular relaxation matrix elements and conditions for this simple T1, T2 description are also given.
Journal ArticleDOI
Temperature- and phase-independent lateral force sensor based on a core-offset multi-mode fiber interferometer.
TL;DR: A novel lateral force sensor based on a core-offset multi-mode fiber (MMF) interferometer is reported that has the advantages of temperature- and phase-independency, high extinction ratio sensitivity, good repeatability, low cost, and simple structure.
