The IRA-3-10 autocorrelator is speciically developed for measuring pulse duration and near contrast ratio of IR ultrafast radiation (wavelength 3–10 μm) that is usually generated by the ultrafast OPAs.
The IRA includes opto-mechanical assembly and electronics with USB interface. System is easy to operate and includes a full set of user friendly software tools for data collection and analysis. Approximation with Gauss and Sech2 proile is also available. The optomechanical assembly consists of optical box and mechanical kit for additional delay of reference pulse.
