Screening charge distribution in pockels readout optical modulators
A voltage is applied through semitransparent electrodes on either side of the structure and then the photoconductor is explosed to light. The photocarriers drift to the photoconductor-dielectric interface under the influence of the applied external field. As a result, an interface charge distribution corresponding to the write-in image light distribution, and screening the field in the photo-conductor is formed
We present what is to our knowledge the most complete 1-D numerical analysis of the evolution and the propagation ::: dynamics of an ultrashort laser pulse in a Ti:Sapphire laser oscillator. This study confirms the dispersion ::: managed model of mode-locking, and emphasizes the role of the Kerr nonlinearity in generating mode-locked ::: spectra with a smooth and well-behaved spectral phase. A very good agreement with experimental measurements ::: of pulse energy, spectrum, and temporal width of extracavity compressed pulses is found.
