Laser Support Services is pleased to offer a range of autocorrelators from Avesta. Both single-shot and scanning autocorrelators are available, with applications in microscopy and FS pulse measurement.
The ASF single-shot autocorrelator is designed for monitoring the pulse duration of ultrafast oscillators and amplifiers, as well as for real-time amplifier systems tuning. The CCD camera registers the transverse section of the non-collinear generation of the second harmonic of the input radiation (the SH is generated in a non-linear crystal). PC USB interface and Windows acquisition software provide for smooth and easy data transition and registration, while additional LabView-compatible drivers offer extended flexibility and on-line control in complex multi-stage experimental setups.
The AA-DD real-time autocorrelator offers smooth and fast measurement of femtosecond and picosecond pulse duration. The autocorrelator can cover several wavelength ranges by using up to 4 interchangeable photodetectors and optics. Two separate ranges can also be covered upon request. Input pulse duration ranges from 10 fs to 30 ps for easy monitoring of different laser systems, especially femtosecond and picosecond oscillators.
The device features USB interface and can be easily hooked up to a PC with Windows OS, LabView drivers are also included in the package. The software is supplied with the device and comprises several useful tools. The acquired pulse duration data can be visualized, stored or exported to a .txt or .dat file. Autocorrelation function and final FWHM pulse duration in femtoseconds are calculated and displayed in real-time. Moreover, Gaussian or sech2 fitting options are available, intensity function may also be observed. The statistical viewer feature allows the comparison of data acquired from several separate pulse measurements.
The tiny body of the AA-DD flawlessly fits any experimental setup with strict space requirements. We also offer an optional fiber input for fast and reliable pulse duration measurement in various optical fibers. Moreover, the autocorrelator in this case still maintains the free-space measurement capability.
