The Femto Easy µ-ROC has become a key tool in our pulse diagnostics toolbox. Thanks to its compact form factor and effortless alignment, it is a highly portable device that we have deployed across various laser systems and beam transport access points—both standalone and in parallel with other diagnostics. It is a versatile and reliable first step in our pulse characterization.

Within the X-ray sources and applications group at the ELI Beamlines Facility, we leverage the user-friendliness and flexibility of Femto Easy devices, including the BeamPro, FROG, ROC and MISS. Their straightforward alignment, intuitive configuration, and seamless all-in-one software are crucial to meeting our needs across multiple experimental stations with different driving lasers and specific user application demands.

Based on our initial weeks of experience using the FemtoEasy MS-ROC and MS-FROG devices, we highly recommend them for light pulse characterisation. These tools combine high sensitivity and compact design with a user-friendly software interface that simplifies data acquisition and export. The flexibility of free-space and fibre optic inputs, combined with responsive and efficient customer service, promises to be a great help to our research team members

Among the autocorrelators we’ve used, MS‑ROC stands out. Setup was effortless and it delivered precise measurements right away. Femto Easy’s support is also top‑tier.

ROC autocorrelator is quite accurate with much more data points and better fitting. And it is also quite easy to use.

We use the ROC single-shot autocorrelator and the BeamPro laser beam profiler from Femto Easy. Those systems are robust and easy to use, hence perfect for a laboratory use with multiple users.

We’ve been using the Femto Easy MS-ROC autocorrelator for a few years now, and it’s been a great addition to the lab. It’s become our go-to for getting precise pulse duration measurements across various R&D and production projects.
With a range of 50 fs to 40 ps, it’s very versatile, easy to align and robust (handling both low and high pulse energies of our high rep rate lasers). It just works.

Thanks to the ease of use of the single-shot ROC Autocorrelator and the BeamPro Laser Beam Profiler, our approach of beam characterization changed dramatically. Given the speed with which reliable results can be obtained and the robustness of the devices, we now use our two Femto Easy instruments for the monitoring of several machines. Technicians can be trained on those devices within an hour thanks to the comprehensive, but non-daunting, manuals. The STAR software is excellent on its own right, and the API makes it simple to integrate Femto Easy devices in our interface.

The BeamPro and MS-ROC Autocorrelator are well equipped to characterize the fs laser for our research lab. The BeamPro provides good quality images and great tracking for beam stability. The MS-ROC has a clear design and is easy to align and measure the pulse width of the beam. The information is saved in convenient formats for further analysis. The STAR software has a clean and customizable interface, yet is packed with features. We appreciate how Femto Easy has implemented our suggestions for improving the software. We look forward to using this equipment for characterizing and monitoring our broad range output OPA and SHG beamlines as we build and use our pump-probe laser system for photoemission orbital cinematography.

The Radio and Optical Communications Lab at DCU acquired the MS-ROC autocorrelator to characterize optical frequency combs from 10 to 100 GHz for applications ranging from data center interconnects to THz generation. Its alignment-free operation achieved through a fibre coupled input to the autocorrelator significantly reduces the time to take our measurements compared to older autocorrelators.

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.

We are using large area beam profilers for the alignment of the optical paths in our machines. The software is easy to use and very intuitive. The combination of the large sensor area with the relatively small footprint of the camera helps a lot for installing the camera in industrial machines where the space is limited. In addition to the cameras, we are also 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.

Our new ROC autocorrelator has proven to be an excellent investment. I appreciate its user-friendly design, from the simple setup process to the intuitive software interface. Plus, its compact size is a definite bonus.

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.

After working with conventional, bulky, and hard-to-operate autocorrelators, I was really impressed by how quick and easy it was to set up and use the µ-ROC. During maintenance and field service of complex ultrafast laser systems—especially on a tight schedule—such a compact and convenient autocorrelator is a must!

The µ-ROC autocorrelator works like a charm! Very good experience, adjustment and full measurement of femtosecond pulses from Ekspla FemtoLux30 laser in just a few minutes – it was really femto easy …

Spark Lasers develops and manufactures high-performance ultrafast lasers, renowned for their excellent pulse temporal quality. One of the keys to achieving this excellence lies in the metrology of our laser sources. To meet our demanding pulse quality goals, we extensively rely on Femto Easy technology. We utilize several systems (Fast FROGs, ROC autocorrelators) in both our R&D and Production departments. Their robustness, ease of use, and performance are instrumental to our daily operations.
