Accurate pulse width measurementswith the APE family of autocorrelatorsAPE offers an autocorrelator product line consisting of three differentautocorrelators - the Mini, the PulseCheck and the Carpe.The Mini is a compact, standard autocorrelator with an integrateddisplay, the ability to operate with low repetition rate lasers, and anRS232 interface. Operating with either high or low repetition rate lasers,the user can easily adjust the Mini to produce noncollinearbackground-free autocorrelation functions, or collinear autocorrelationfunctions of either type: intensity or fringe resolved. The measurementrange spans from femtoseconds up to a few picoseconds with anumber of standard wavelength ranges available.The PulseCheck is a very flexible autocorrelator that is operated froma dedicated electronic controller with a color LCD display. In addition tothe features of the Mini, the PulseCheck measures pulsewidthsfrom femtoseconds up through hundreds of picoseconds in differentdelay versions, while it covers a broader range of wavelengths.Amongst the optional features available for this autocorrelator are aspectrometer and a FROG option, converting the autocorrelatorPulseCheck into a measuring device which allows the most detailedanalysis of the ultrafast pulse.Designed specifically for laser microscopy the Carpe providesinformation about the pulse length of the ultrafast laser beam beforeand after it passes a microscope. It is necessary to detect theconsiderable broadening of the laser pulse caused by the dispersion ofthe optical material in a microscope, because it changes and degradesthe test conditions.Ultrafast Pulse Diagnosticswww.skphotonics.com 102 성경포토닉스Your Partner in Ultrafast
