The Femto Easy µ-ROC autocorrelator is a very compact and user-friendly device. It is easy to align and its compact size allows us to measure femtosecond pulses outside the laboratory where no optical table is available.
Pierre DeslandesCTO, VP and Founder - Ilasis - France
The femtosecond pulse duration measurement solution from Femto Easy (ROC autocorrelator) is easy to use, fast and reliable. The STAR software also establishes a new standard in terms of user friendliness and ease of use.
Beat JäggiActivity Manager Service - Lasea - Switzerland
We are using the ROC autocorrelator. The device is easy to align and perfectly suited for temporary installation in a machine, due to its compact size. In case of problems and questions, the customer support of Femto Easy is reactive and provides good solutions.
Valentin MaffeisLaser process R&D Engineer - HEF - France
Thanks to the ease of use of the single-shot ROC Autocorrelator, our approach of beam characterization changed dramatically. Given the speed with which reliable results can be obtained and the robustness of the device, we now use our Femto Easy instruments for the monitoring of several machines. The STAR software is excellent on its own right, and the API makes it simple to integrate Femto Easy devices in our interface.
Laurent GallaisProfessor - Institut Fresnel - France
We use the ROC single-shot autocorrelator from Femto Easy. This systems is robust and easy to use, hence perfect for a laboratory use with multiple users.

1 Pulse duration
The two minimum pulse duration values correspond to the Fourier limited pulse duration with and without GDD precompensation
2 Input average power / pulse energy min
Values give an order of magnitude, exact sensitivity depends on parameters such as pulse duration, repetition rate, beam diameter, 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.
