Spatial separation of large dynamical blue shift and harmonic generation [PDF]
, 2006 We study the temporal and spatial dynamics of the large amplitude and frequency modulation that can be induced in an intense, few cycle laser pulse as it propagates through a rapidly ionizing gas. Our calculations include both single atom and macroscopic

IET Power Electronics, 2023 The excessive fluctuation of the floating capacitance's (FCs) voltage affects the output performance and output power of the 3P‐5L‐ANPC converter. In order to minimize the fluctuation of the FCs voltage, an optimization control method based on zero ...

The High Time Resolution Universe Survey - V: Single-pulse energetics and modulation properties of 315 pulsars [PDF]
, 2012 We report on the pulse-to-pulse energy distributions and phase-resolved modulation properties for catalogued pulsars in the southern High Time Resolution Universe intermediate-latitude survey. We selected the 315 pulsars detected in a single-pulse search

A modulator for discrete trains of pulses [PDF]
Electroencephalography and Clinical Neurophysiology, 1965 Abstract A circuit is described which provides a means of modulating trains of pulses of duration from 1 msec up to 1.5 sec. This device was especially designed for use with Grass Instruments Co. stimulators so that only one stimulator is needed for generating trains of pulses.

Actively Q-Switching in the Intra-Cavity Pumping Mechanism for Polarized Oscillation at 2.1
IEEE Access, 2020 Q-switched and polarized Ho lasers are the ideal driving source for mid-infrared radiation via optical parametric oscillation. Although intra-cavity pumping is an efficient way to achieve the Ho laser oscillation at 2.1 μm, which also facilitates ...

Phase modulation induced by cooperative effects in electromagnetically induced transparency
, 2010 We analyze the influence of dipole-dipole interactions in an electromagnetically induced transparency setup at high density. We show both analytically and numerically that the polarization contribution to the local field strongly modulates the phase of a

Modulation effect in multiphoton pair production
Physics Letters B, 2017 We investigate the electron–positron pair production process in an oscillating field with modulated amplitude in the quantum kinetic formalism. By comparing the number density in the oscillating field with and without modulation, we find that the pair ...

A Chaotic Pulse-Time Modulation Method for Digital Communication
Abstract and Applied Analysis, 2012 We present and investigate a method of chaotic pulse-time modulation (PTM) named chaotic pulse-width-position modulation (CPWPM) which is the combination of pulse-position-modulation (PPM) and pulse-width modulation (PWM) with the inclusion of chaos ...
