An Intelligent Instrument for Ultrashort Laser Pulsewidth Measurement

An intelligent instrument used for measuring the width of ultrashort laser pulse is presented. Combining with a noricollinear SHG correlator, time resolution of 0.1 psec or better can be obtained. The measured results can be printed out on a printer and the graph can be plotted with a personal plotter or displayed on an oscilloscope. With the help of this instrument, an automatic measuring system used for other purposes can be easily constructed.
