Amplified low-repetition-rate fs pulsewidth measuring and DLA caused pulse broadening

Amplified low-repetition-rate fs pulse is generated with dye laser amplifier(DLA). The pulsewidth is measured with a computer-aided autocorrelator and the fs pulsewidth broadening caused by the dispersion of the DLA is analyzed. Furthermore, the autocorrelator introduced in this paper could be used as a low scanning autocorrelator to measure high-repetition-rate pulsewidth.

Study of synchronously mode-locked and internally frequency-doubledcw dye laser

The analysis of the characteristics of a synchronously mode-locked and internally frequency-doubled dye laser is presented. Dependence of dye laser pulse characteristics on the cavity length mismatch of the pump laser and dye laser is studied. Variation of the minimum pulsewidth with intracavity bandwidth and the harmonic conversion efficiency is presented in the form of graphs.     

The influence of electron intervalley transfer on response pulse width of the MSM photodetector

This paper analyses the influence of nonstationary effects on response pulswidth of Metal-Semiconductor-Metal Photodetector (MSM-PD) made of a two-valley semiconductor. A phenomenological model is used for 2D numerical simulation of carrier transport and intervalley transfer. The analysis of the pulsewidth response of the MSM-PD has been made for various micron and submicron structures, bias voltages and incident light wavelengths.     

Simultaneous compression of the pulsewidth and pulse train of a passively mode-locked Nd:YAG laser

Simultaneous compression of the pulsewidth and the pulse train of a passivelymode-locked Nd:YAG laser has been achieved by using a plano-convex unstable resonatorwith a nonlinear Sagnac ring interferometer.A single pulse energy of >30mJ and apulsewidth of ≤10ps have been obtained.Using this system,the LAGEOS and ETALONsatellites laser ranging have been performed successfully.
