EKSPLA introduced new line of products - AC series picosecond scanning autocorrelators. Autocorrelators of AC series are designed for the measurement of pulse duration of ultrafast lasers using the non-collinear second harmonic generation technique.
Standard AC series models are targeted to work with mode-locked or SBS‑compressed Nd:YAG or Nd:YLF lasers at fundamental or second harmonic wavelength. A double‑wavelength model is available as well. The autocorrelator can be built to accept input wavelengths in the 420–2000 nm range on request. The scanning range can be extended from standard ±300 ps to ±1200 ps for longer pulse duration measurements or for more detailed pulse shape characterisation (for example, the measurement of satellites of the main pulse).
Software supplied together with the autocorrelator allows for automated, hands-free measurement. The user can set the scanning step and range, the number of pulses averaged, and other parameters. The installed input pulse energy monitor allows the user to gate incoming pulses by their energy, making sure that laser instabilities do not influence the result.
