Cross-correlator COMET
zoom in

The new third order cross-correlator has been specifically developed for measuring a wide array of output parameters from ultrafast laser systems including: contrast ratio of laser pulses, determining pulse pedestal, pre- and post-pulses, and amplified spontaneous emission in femtosecond systems. It also provides information about the third-order cross-correlation function of pulse intensity on a femtosecond scale and can be used for alignment of high power femtosecond lasers.

The cross-correlator includes an opto-mechanical assembly and electronics with USB interface. The system is easy to operate and includes a full set of user friendly software tools for data collection and analysis.
