Revealing of Li-Ion Transportation in Crystal Lattices by 7Li SAE in Solid-State NMR
Chinese Journal of Magnetic Resonance, 2020 Spin alignment echo (SAE) is employed here to study the α-LiAsF6/PEO6 system with low poly(ethylene oxide) (PEO) molecular weight. We show that the correlation rate kSAE from SAE experiments, but not the spin-lattice relaxation time and the linewidth, is

Laser Linewidth Compression in Cascading Brillouin Random Fiber Lasers
IEEE Photonics Journal, 2022 Cascaded Brillouin random fiber lasers (BRFLs) with laser linewidth compression were theoretically and experimentally demonstrated. Thanks to photon-phonon coupled interplay as well as randomly distributed feedback along silica fibers, the coherent time ...

Acta Physica Sinica, 1964 In this paper, the "short-time" part of the linewidth of a laser beam has been considered with the fundamental equations which describe the behaviours of lasers. This linewidth is described usually by △vs=(8πhv(△v′)2)/P, (1) here △v′ is the half-width of the electromagnetic mode of cavity, v the beam frequency, and P the output power.

Optical linewidth of soliton microcombs
Nature Communications, 2022 Abstract Soliton microcombs provide a versatile platform for realizing fundamental studies and technological applications. To be utilized as frequency rulers for precision metrology, soliton microcombs must display broadband phase coherence, a parameter characterized by the optical phase or frequency noise of the comb lines and their ...

Optical parametric oscillators : a comparison of new materials [PDF]
, 2015 A study of new materials for optical parametric oscillators (OPOs) was carried out using an XeCI excimer laser as a pump source. The three non-linear optical materials studied were lithium borate (LBO), deuterated L-arginine phosphate (d-LAP) and β ...
