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

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 ...

RF or THz signals generated from DC biased multimode lasers [PDF]
, 2007 Although self pulsating (SP) lasers are DC biased, they feature a modulation of the output power. For the results presented in this paper, the SP frequency corresponds to the frequency spacing between longitudinal modes or its second harmonic.
