µ-ROC
Worlds smallest autocorrelator

Pulse duration measurement made easy
Ti:Sa | Yb
Single-shot
get immediate results even on single-pulses
Alignment free
saves up to 90% time compared to conventional autocorrelators
Robust design
No moving parts, non sensitive to vibrations
Spatially-resolved measurements
Measurement of beam profile and pulse duration distribution over one diameter
Discover the autocorrelator in miniature form
The µ-ROC marks the start of a new era of compact size without compromise. It impresses with its miniature form and high-quality workmanship and brings autocorrelation measurements directly into machines, lasers, medical equipment and everywhere where little space is available.

1 Pulse duration
The two minimum pulse duration values correspond to the Fourier limited pulse duration with and without GDD precompensation
2 Input pulse energy min
Values give an order of magnitude, exact sensitivity depends on parameters such as pulse duration, beam profile, wavelength…
3 Single-pulse
Up to 100 kHz laser repetition rate with Trigger option, 50 kHz without
Software
The Femto Easy software has been designed to be user friendly and intuitive. This is a modern software compatible with touchscreen that can run either under Linux or Windows. It allows distant control of the devices via PC, tablet or smartphone. We can also provide custom software developments upon request.
