Cw X-ray Preionized Pulsed Gas Lasers
We have successfully demonstrated that the cw x-ray generator can work as a preionization source for a pulsed H F laser. The preionization effect of cw x radiation was revealed by a comparative study of with and without applying x-ray photons to the H F laser. Since dose rate of the cw x-ray generator is easily controllable, the laser output could be measured as a function of initial electron n...
متن کاملRoles of Fluctuations in Pulsed Neural Networks
Concerning the fluctuation which is observed in biological sensory systems and cortical neuronal networks, the roles of fluctuations in pulsed neural networks are investigated. As a model of a single neuron, the FitzHugh-Nagumo model is used, and two kinds of couplings of neurons are considered, namely, the electrical coupling which is often observed in sensory systems, and the chemical couplin...
متن کاملDetailed characterization of CW- and pulsed-pump four-wave mixing in highly nonlinear fibers.
We present a quantitative comparison of continuous-wave- (CW) and pulsed-pump four-wave mixing (FWM) in commercially available highly nonlinear fibers (HNLFs), and suggest properties for which the CW- and pulsed-pump FWM bandwidths are limited in practice. The CW- and pulsed-pump parametric gain is characterized experimentally for several HNLFs with various dispersion properties, including zero...
متن کاملInvestigating the Transmission of Financial Stress Index Fluctuations on Macroeconomic Indicators of Selected Opec Member Countries
Stress in financial markets is defined as the force influencing the behavior of economic agents in the form of uncertainty and changing expectations, the critical values of which are called financial crisis. Increasing oil revenues may have positive effects on aggregate supply through increased investments, especially public sector investment, as well as the import of capital and intermediate...
متن کاملSynthetic aperture radar raw signal simulator for both pulsed and FM-CW modes
Simulated raw radar signals prove to be very useful at the first stages of testing radar signal processing algorithms and procedures. This is particularly true for synthetic aperture radar (SAR), where the costs of real signals acquisition are very high due to the costs of building the system as well as the costs of mission (air or space-borne). This paper describes a multifunctional SAR raw si...
