Features

  • 50 fs - 250 ps broad input pulse duration range
  • 450 nm - 11000 nm input wavelength range
  • USB interface and Windows software included in a standard package

Applications

  • Femtosecond oscillator pulse duration measurement
  • Femtosecond pulse duration measurement and dispersion characterization
  • Femtosecond and picosecond pulse duration and near contrast measurement
  • Novel ultrafast fiber laser development
  • Femtosecond and picosecond OPA pulse duration and near contrast measurement
  • Amplifier design

The IRA scanning autocorrelator is specifically developed for the measurement of pulse duration and the 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.
