The TVS-EPA series autocorrelator is a device used to measure ultrafast laser systems with pulse widths of femtosecond and picosecond. The principle of its measurement is to superimpose signal pulses with in-phase pulses with variable time delay, so that the two pulses overlap in the detector, and then record the generated autocorrelation trajectory. The pulse duration can be determined by measuring the generated fringe interference signal. This product is based on the principle of two-photon absorption effect of photodetectors, and has the advantages of a wide measurement range (400-1800 nm), insensitivity to input polarization, and fast and simple adjustment. It is an ideal tool for pulse width measurement in femtosecond and picosecond laser systems.
