Characterization of the frequency stability of frequency-hopping sources
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1991A method that applies time-domain stability measures, hitherto used only in the context of fixed-frequency sources, to the characterization of frequency-hopped sources is introduced. This method has been successfully applied to the testing of a novel practical frequency-hopping synthesizer. It is shown that despite the fact that hopping sources exhibit

Frequency Stabilization of a Gas Laser
Applied Optics, 1969The frequency of a gas laser was stabilized by making use of the competition between the oppositely circularly polarized components of a single cavity mode of a laser in an axial magnetic field. For appropriate transitions the coupling between the polarizations leads to a sharp crossover in their intensities as the cavity is tuned across the center of ...

Frequency stability of a Zeeman-stabilized laser
Applied Optics, 1985The frequency of a commercial hard-sealed He–Ne laser has been stabilized to the center of the discharge gain profile using the mode splitting caused by an axial magnetic field. The absolute frequency has been measured repeatedly during intermittent operation over 20 months. Its drift over most of this period has been 2.6 ± 0.7 MHz/yr.

Frequency Stability Constrained BESS Sizing Model for Microgrids
IEEE Transactions on Power SystemsThe grid integration of renewable energy sources necessitates using energy storage systems (ESSs) to provide more flexibility and controllability. This article proposes a frequency stability-constrained battery energy storage system (BESS) sizing model ...

Most of the new renewable generation in power systems is connected through Grid-Following inverters (GFL). The accompanying decline of fossil-fuelled synchronous generation reduces the grid inertia. As these two trends progress, instabilities become more

Most existing studies on probabilistic frequency stability analysis ignore the dynamics of wind power generations (WPGs) and thus result in inaccurate analysis results especially when the fast frequency response of WPGs is expected. This paper proposes a

Frequency stability and stabilization of a chemical laser
IEEE Journal of Quantum Electronics, 1978We have built a low-power CW HF/DF chemical laser, designed to achieve high-frequency stability. Measurements are reported which characterize the instantaneous spectral width of the laser output to less than one part in 1011( \Delta\nu kHz) and the variations in absolute frequency of this emission with time to four parts in 1010( \Delta\nu = \pm20 kHz)
