PulseCheck

Request a quotation

Our pulseCheck autocorrelator is a versatile instrument for measuring the pulse width of different fs and ps laser systems, with the ability to cover a broad wavelength range. 

Depending on the wavelength range and the repetition rate, additional options such as FROG measurement and separate spectrometers are available. The wavelength range can be upgraded in the field. Please ask us which upgrades are possible.
 A·P·E also offers customer-specific modifications. As with all A·P·E autocorrelators, pulseCheck is easy to install and use.

Features: 

  • Femtosecond resolution
  • All-reflective optics
  • Measurement of background free and interferometric autocorrelation functions
  • PC interface
  • Windows control software included
  • Wide measuring range
  • Display of width of autocorrelation function
