µ-ROC | World’s Smallest Single-Shot Autocorrelator

ROC stands for Row Optical Correlator. Utilizing an exceptionally compact and robust inline setup, the μ-ROC pushes the boundaries of single-shot autocorrelation principles to enable fast and super compact measurements of of ultrafast laser pulses. Developed using Femto Easy’s newest patented design and drawing upon extensive expertise in single-shot ultrafast pulse instrumentation cultivated over numerous years, the μ-ROC sets a new standard in single-shot autocorrelator performance, engineered for effortless OEM integration directly into laser heads or laser systems.

Features:

µROC single shot autocorrelator

Ultra compact autocorrelator, non sensitive to alignment, can be used as a simple camera
Measurement of ultrafast laser pulses from 20 fs to 1500 fs
Robust design, no moving parts. Insensitive to vibrations
No power supply needed, directly powered by the USB cable
Suitable for any repetition rate.
Single-pulse extraction possible up to 100 kHz laser repetition rate (with Trigger option)
User-friendly and powerful software.
REST API for standard software integration using simple HTTP requests
Trigger option available

The introduction of the µ-ROC marks a new era of compact technology without sacrificing quality. Its small size and exceptional craftsmanship make a striking impression, seamlessly integrating autocorrelation measurements into machinery, laser systems, medical equipment, and any space-constrained environment.

*The two minimum pulse duration values correspond to the Fourier limited pulse duration with and without GDD precompensation.

**Those values give an order of magnitude. The exact sensitivity depends on many parameters (pulse duration, beam profile, wavelength…)
