Ultra-narrow linewidth Brillouin laser with nanokelvin temperature self-referencing
Optica, 2019 Ultrastable lasers serve as the backbone for some of the most advanced scientific experiments today and enable the ability to perform atomic spectroscopy and laser interferometry at the highest levels of precision possible. With the recent and increasing

High Power Laser Science and Engineering, 2023 In this work, we experimentally investigate the dependence of the stimulated Raman scattering (SRS) effect on the seed linewidth of a high-power nanosecond superfluorescent fiber source (ns-SFS). The results reveal that the SRS in the ns-SFS amplifier is

Spectroscopy of the $^1S_0-{}^3P_0$ Clock Transition of $^{87}$Sr in an Optical Lattice
, 2003 We report on the spectroscopy of the $5s^2 {}^1S_0 (F=9/2) \to 5s5p {}^3P_0 (F=9/2)$ clock transition of ${}^{87}{\rm Sr}$ atoms (natural linewidth of 1 mHz) trapped in a one-dimensional optical lattice. Recoilless transitions with a linewidth of 0.7 kHz

Dzyaloshinskii-Moriya interaction induced extrinsic linewidth broadening of ferromagnetic resonance
, 2017 For a thin ferromagnetic film with the Dzyaloshinskii-Moriya interaction (DMI), we derive an expression of the extrinsic ferromagnetic resonance (FMR) linewidth in a quantum mechanical way, taking into account scatterings from structural inhomogeneity ...

Trade-off between Linewidth and Slip Rate in a Mode-Locked Laser Model
, 2014 We demonstrate a trade-off between linewidth and loss-of-lock frequency in a mode-locked laser employing active feedback to control the carrier-envelope offset phase difference.

Linewidth of the electromagnetic radiation from Josephson junctions near cavity resonances
, 2013 The powerful terahertz emission from intrinsic Josephson junctions in high-Tc cuprate superconductors has been detected recently. The synchronization of different junctions is enhanced by excitation of the geometrical cavity resonance.

Narrow resonances with excitation of finite bandwidth field [PDF]
, 1998 The effect of the laser linewidth on the resonance fluorescence spectrum of a two-level atom is revisited. The novel spectral features, such as hole-burning and dispersive profiles at line centre of the fluorescence spectrum are predicted when the laser ...

Diatomic predissociation linewidths [PDF]
, 1974 Predissociation by rotation and curve crossing in diatomic molecules is discussed. The pattern of predissociation line widths is seen as providing a highly sensitive yardstick for the determination of unknown potential curves. In addition, the computation of such a pattern for given potential curves is considered a matter of routine, unless the ...
