|* - each subrange is covered by an exchangeable optics set (NL crystals, beamsplitters, filters, photodetectors). A set for one of the subranges of the customer's choice is supplied with the unit, additional sets are supplied upon request; the final set of optics and detectors depends on the specifications of the sources to be measured and is discussed with our sales manager upon offering;
** - typical values, depends on input pulse duration and wavelength.
The IRA scanning autocorrelator is specifically developed for measurement of pulse duration and near contrast ratio of ultrafast radiation generated by ultrafast amplifiers and oscillators. There is also a special model of the IRA system that is suitable for mid-IR laser sources.
The IRA includes opto-mechanical assembly and electronics with USB interface. The system is easy to operate and includes a full set of user friendly Windows software tools for data collection and analysis. Approximation with Gauss and Sech^2 shapes is also available. The unit implements a robust scanning mechanism.
The acquisition and analysis software is fully compatible with Windows, USB drivers are included

Avesta’s facilities will be closed for the New Year break from 30 Dec 2017 till 08 Jan 2018. We will resume all operations on 09 Jan 2018. However, we hope to provide periodic e-mail correspondence during the holidays. We wish you a fruitful and prosperous Year 2018!
Avesta is participating in the “LASER World of PHOTONICS 2017” (Munich, Germany, 26-29 June 2017) trade show. Feel free to drop by our booth B2.151 to see the TeMa Yb laser system along with the AA-20 autocorrelator and GECON supercontinuum generator. The trade show participation is supported by the Russian Export Center and organized by Expocenter and Russian Laser Association.
