The IRA-3-10 autocorrelator is an advanced instrument meticulously engineered to measure the pulse duration and near contrast ratio of infrared (IR) ultrafast radiation, specifically within the 3–10 μm wavelength range. This radiation is typically produced by ultrafast Optical Parametric Amplifiers (OPAs). The device is a complete solution that includes an opto-mechanical assembly and electronics, all interfaced via USB for seamless integration and operation. With its intuitive design, the system offers a full suite of user-friendly software tools for efficient data collection and analysis, including approximation capabilities with Gauss and Sech² profiles.

The opto-mechanical assembly of the IRA-3-10 consists of an optical box and a mechanical kit designed to provide additional delay of the reference pulse, ensuring precise measurements. Its acquisition and analysis software is fully compatible with Windows XP, and all necessary USB drivers are included for straightforward setup. This ensures that users can operate the system with minimal technical hurdles, focusing instead on obtaining accurate and reliable data.

With its robust construction and comprehensive software package, the IRA-3-10 autocorrelator is an ideal choice for researchers and professionals working with IR ultrafast radiation. Its design emphasizes ease of use without compromising on the precision and reliability necessary for high-stakes scientific measurement. This makes the IRA-3-10 a valuable tool in the arsenal of any laboratory engaged in cutting-edge photonics research.
