Determination of Carrier-Envelope Phase of Relativistic Few-Cycle Laser Pulses by Thomson Backscattering Spectroscopy
Carrier-Envelope Phase ew-Cycle Laser Pulses Thomson Backscattering Spectroscopy
2011/9/2
A novel method is proposed to determine the carrier-envelope phase (CEP) of a relativistic few-cycle laser pulse via the central frequency of the isolated light generated from Thomson backscattering (...
Carrier-envelope phase sensitive inversion in two-level systems
Carrier-envelope phase sensitive two-level systems
2011/9/2
We theoretically study the carrier-envelope phase dependent inversion generated in a two-level system by excitation with a few-cycle pulse. Based on the invariance of the inversion under time reversal...
Modulation Instability of Ultrashort Pulses in Quadratic Nonlinear Media beyond the Slowly Varying Envelope Approximation
Quadratic Nonlinear Media Theoretical model and MI analysis
2011/8/31
We report a modulational instability (MI) analysis of a mathematical model appropriate for ultrashort pulses in cascaded quadratic-cubic nonlinear media beyond the so-called slowly varying envelope ap...

Carrier-Envelope Phase Effects Multi-Photon Excitation
2010/11/9
We present an experimental and theoretical study of multi-cycle pulse coherent control by carrier-envelope phase(CEP) under bichromatic radio-frequency(RF) field excitation. Using intense ultra-short...
Envelope Soliton Oscillator for UWB
Envelope Soliton Oscillator nonlinear transmission line
2010/4/6
An electronic oscillator is shown to support an envelope soliton pulse. The oscillator comprises a loop, formed by a nonlinear transmission line, an amplifier, a bandpass filter and a saturable absorb...

An Analysis of the Variation in Calculated Confined-State Energies Using Different Envelope-Function Models
Calculated Confined-State Energies Different Envelope-Function Models
2010/4/19
We investigate different formulations of the envelope-function method and show that the accuracy of the calculated zone-centre confinement energies can be calculated by means of bulk band structure. W...
