Single Shot Autocorrelator ASF

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) with a sensitivity < 1 µJ.

Description 

Features

  • Possible wavelength range from 400 nm to 2200 nm
  • 5 fs to 15 ps possible pulse duration measurement
  • USB interface with Windows PC software and LabView drivers in a standard package
  • CCD 2D detector for precise data acquisition with lowest error
  • 1 µJ single-shot sensitivity

Applications

  • Femtosecond oscillator pulse duration measurement
  • Comparison of dispersion values, determining dispersion of various optical elements
  • Femtosecond and picosecond pulse duration and near contrast measurement
  • Femtosecond and picosecond OPA pulse duration and near contrast measurement
  • Single-shot femtosecond pulse duration measurement
  • Amplifier design
  • Automation of complex experimental setups

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.

There are four basic models of the ASF family covering a broad possible operating wavelength range.

The ASF-5 system allows measurements of few-cycle pulses with pulse duration as short as 5 fs. The system is based on non-dispersive beam splitting technique providing best accuracy for few-cycle pulse measurement.

The ASF-15 system is a compact unit for routine characterization of low-repetition-rate ultrafast amplifier output as well as seed oscillator output in the range of 15 fs to 200 fs.

The ASF-50 and the ASF-200 units offer extended longer pulse duration measurement limit for ultrashort-pulse amplifier development and tuning. The ASF-200 unit is also used for precise control of pulse duration at the output of commercial laser systems with a tunable compressor unit.

Please feel free to enquire about custom pulse durations and wavelength ranges.
