There are several commercially available autocorrelators on the market such as the Spectra-Physics PulseScout2™. They are usually designed to measure pulses from a few femtoseconds to several picoseconds in duration. Very often, however, there is a need in research labs to combine the capabilities of measuring very short pulses in the range of tens of femtoseconds with the capability of measuring long pulses on the order of tens of picoseconds with femtosecond resolutions. A typical example is the stretching of a femtosecond pulse to many picoseconds for experiments where large bandwidths are required or chirped pulse amplification. More than just measuring ultrashort pulses, autocorrelators can be used to detect signals in time regions relatively inaccessible by most detectors.

All of the components included in this kit have been tested in combination with Spectra-Physics Ultrafast Ti:Sapphire oscillators, amplifiers and optical parametric devices by the Scientists in Newport's Technology and Applications Center. In contrast to commercially available autocorrelators, the Newport long scan autocorrelator kit is suitable for beam diameters up to 10 mm. The dynamic range of the detection system allows contrast measurements up to 7000:1. The kit also includes reference software that can be customized for user's application. Please contact us about special versions of the kit with longer delay (up to ± 160 ps) and/or longer wavelength range if needed.
