Pulsed Optically Pumped Rubidium Clock With High Frequency-Stability Performance [PDF]

open access: yes, 2012
In this paper, we present the performance of a vapor-cell rubidium frequency standard working in the pulsed regime, in which the clock signal is represented by a Ramsey pattern observed on an optically detected laser absorption signal.

Current limitations of cryogenic microwave oscillator frequency stability [PDF]

open access: yes, 2014
Technical paperCryogenic microwave oscillators built upon sapphire loaded cavity resonators exhibit excellent levels of frequency stability. Here we present an overview of the current understanding of the various processes and noise sources that limit ...

Planar-Waveguide External Cavity Laser Stabilization for an Optical Link with 1E-19 Frequency Stability [PDF]

open access: yes, 2011
We stabilized the frequency of a compact planar-waveguide external cavity laser (ECL) on a Fabry-P\'erot cavity (FPC) through a Pound-Drever-Hall scheme.

An optical fibre-based frequency dissemination network for Australia [PDF]

open access: yes, 2011
An optical-fibre network is being planned for distribution of optical and microwave reference frequencies in Australia. This network would connect a number of research facilities and the National Measurement Institute (NMI), allowing long-range ...

Stabilization of grid frequency through dynamic demand control [PDF]

open access: yes, 2007
Frequency stability in electricity networks is essential to the maintenance of supply quality and security. This paper investigates whether a degree of built-in frequency stability could be provided by incorporating dynamic demand control into certain ...

Influence of absorption on stability of terahertz difference frequency generation [PDF]

open access: yes, 2016
This work presents numerical studies of the stability feature of terahertz difference frequency generation (THz-DFG) with a ZnGeP2 crystal using two pump wavelengths. We found that the maximum output of a THz wave is located in the unstable output region

Pulsed optically pumped Rb clock with high frequency stability performances [PDF]

open access: yes, 2011
In this paper we present a prototype of Rb clock working in pulsed regime with high freq stability performances. In particular, a frequency stability as low as 1.6×10-13τ -1/2 has been measured for integration times up to 105 s.

Robust Stability of Multivariate Polynomials, Part 3: Frequency Domain Approach [PDF]

open access: yes, 2000
A new formulation of thezero exclusion principle is presented and it is applied to thestudy of robust stability of multivariate polynomials. It hasbeen proven that the stability radius of a stable polynomialcoincides with its strict sense stability ...

A frequency-domain approach to the analysis of stability and bifurcations in nonlinear systems described by differential-algebraic equations [PDF]

open access: yes, 2007
A general numerical technique is proposed for the assessment of the stability of periodic solutions and the determination of bifurcations for limit cycles in autonomous nonlinear systems represented by ordinary differential equations in the differential ...

Rotor angle stability with high penetrations of wind generation [PDF]

open access: yes, 2012
This paper explores the relationship between wind generation, particularly the control of reactive power from variable speed wind turbine generators, and the rotor angle stability of the conventional synchronous generators in the system.
