Linewidth for fluxon oscillators
Soliton perturbation theory is used to calculate the fluxon oscillator linewidth arising from fluxon interaction with background radiation. Detailed calculations in the case of an oscillator that is long compared with the Josephson length and for which the radiation field is thermal establish lower bounds for the linewidth of a real oscillator.

Tunable passively Q-switched ultranarrow linewidth erbium-doped fiber laser
A tunable passively Q-switched erbium-doped fiber laser with ultranarrow linewidth is proposed and demonstrated. With the single wall carbon nanotubes (SWCNTs) as the passive Q-switch, the ultranarrow linewidth laser operation is realized based on ...

Homogeneous linewidth and linewidth enhancement factor for a GaAs semiconductor laser
The homogeneous linewidth and the linewidth enhancement factor alpha for a room-temperature GaAs laser are studied, calculating the time constant for the relaxation of the polarisation. The homogeneous linewidth obtained, arising from electron-electron and electron-phonon interactions, is of the order of several meV.

Magnetic Field Dependence of Spectral Correlations between 31P-Containing Metabolites in Brain
Spectral correlations between metabolites in 31P magnetic resonance spectroscopy (MRS) spectra of human brain were compared at 3 and 7 Tesla, the two commonly used magnetic field strengths for clinical research. It was found that at both field strengths,
