Pascal DupriezCEO - Spark Lasers - France
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.
Patrick Bowen MontagueR&D Manager - NKT Photonics - Denmark
Femto Easy’s FROGs are the most versatile tools available on the market. For our research purposes, the ability to cover broad bandwidth ranges with both fs and ps duration pulses made them ideal. The Femto Easy team also provides fast support and training on the equipment, which experienced FROG users will understand is crucial. The software produces accurate retrievals even in complex or low signal environments.
Maksim LivshitsStaff Scientist - Los Alamos National Laboratory - USA
I currently have three different FROGs and the Femto Easy Single Shot FROG is the easiest, most reliable FROG to use. Femto Easy has made a stable software release (not compiled LabVIEW homebrew code) that reliably connects to FROG hardware. Femto Easy FROG hardware is quick and easy to align with one adjustment point saving time during setup. The phase retrieval algorithm is reliable providing the same quality as a traditional scanning frog. The FROG trigger option works well with my low rep rate amplifier enabling versatility between my 1 kHz and 10 Hz Ti:sapphire amplifiers.

We have been using our MS-FROG with great satisfaction. Compared to other FROG systems we’ve worked with, the Femto Easy system demonstrates significantly better contrast and exceptional spectral performance. It has been immensely helpful in accurately characterizing our 2 nm bandwidth ultrafast laser. Based on this, we plan to utilize your system as a reference tool to monitor the long-term pulse shape stability of our laser.
Maximilian BradlerTechnology Manager - Menlo Systems - Germany
The Femto Easy MS-FROG is a reliable and easy usable tool to characterize our high repetition rate (250 MHz) femtosecond pulses at 1550 nm. The fiber coupling ensures a straightforward measurement and the software allows a fast retrieval of the pulse duration and spectral phase. We mainly use it during our laser production. Also great thanks for the fast and helpful communication and support.
Chengyong FengResearcher - LLE University of Rochester - USA
Our MISS imaging spectrometer is very easy to use and much more compact than the other similar systems we have in our group. I also appreciate the very quick support from the team.
Senior Expert - Laser & OpticsConfidential Medical Company
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.
ASMLSenior Researcher - ASML - The Netherlands
With the Femto Easy FROG we went from unboxing to in-depth system learning in less than 1 hour. The system is intuitive to align and operate when compared to other similar systems in our facility.
Florent MargaillanOptical Engineer - NanoSciences Institute of Paris - France
The single-shot FROG is an ideal solution for characterization of kHz Ti:Sapphire amplifier with pulse duration of around 30 fs (achromatic design by using a bimirror). I particularly appreciated the consideration of my specific request on the wavelength range in order to characterize both the pump laser and the OPA signal. If the quality of the software is often highlighted, I also valued the overall finish of the device and its mechanical parts.
Enrico RidenteLaser Engineer - Infleqtion - UK
Our FROG system has been working amazingly ! We found the interface user-friendly and simple to use.
Roland NagymihályArea manager of High Field Laser Laboratory - ELI ALPS - Hungary
Our MISS-Broadband-L and MISS-VSWIR imaging spectrometers are extremely useful to diagnose our few-cycle light sources, even after post-compression. The spatio-spectral resolution allows to check the pulse quality both in near and far field, that gives an unmatched performance for measuring the spatio-spectral distortions of ultrashort pulses.
Beat JäggiActivity Manager Service - LASEA - Switzerland
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.
Frederick BörgmannLaser Engineer - Edgewave - Germany
I am very happy with the Femto Easy FROG device. The ease of use and the software are absolutely great for fast lab work. I was especially successful in a project where our classic autocorrelator was performing badly due to saturation effects at low frequencies and I had no problems whatsoever using this device. My main use is compressor adjustment and the live measurement is great for that as well.
Gwenaëlle VaudelHead of instrumental platform - IMMM - France
I’m in charge of an instrumental platform comprising several experimental benches based on multiple femtosecond laser sources (35-200 fs, 400 nm to 2.6 µm wavelength). I therefore purchased two Femto Easy products (a beam profiler and a single-shot FROG) to characterize the beams. Their wavelength flexibility, ease of use and speed are real assets. We regularly use the FROG when building new setups to check the evolution of our pulse widths or to adjust our pre-compensation setups. Those instruments have become essential tools on our platform.
Martin MaurelResearcher - Teraxion - Canada
A few years ago, I had the privilege of testing the very first FROG prototype that Antoine delivered using his motorcycle at the time. Now, on a different continent, I regularly work with the FROG at 1030 nm. Being in an RD lab, the flexibility to move the measurement device without the inconvenience of extensive realignment is simply fantastic.
We use this equipment regularly, and the amplitude and phase reconstruction occur swiftly and with high precision. The single-shot feature has revolutionized our experiments by enabling us to actively and instantly cancel the residual spectral phase reconstructed by the algorithm, while simultaneously feeding our TPSR (tunable pulse stretcher) in real-time. The Femto Easy team is always there for us, ready to address our inquiries and provide assistance – something we truly appreciate.
Pierre DeslandesCTO, VP and Founder - Ilasis - France

Arnaud GuillossouSenior Laser & Optics Engineer - Bloom Lasers - France
We got the opportunity to try different models of BeamPro for our IR, green and UV lasers and all the cameras meet our specifications. Each camera has its own differentiation, from LP6.3 with its tiny pixels, to BP12.12 with its large sensor. The STAR software is easy to use, intuitive, and very responsive compared to other laser beam profiler suppliers
Nathalie VermeulenProfessor - Vrije Universiteit Brussel - Belgium
As a customer of Femto Easy, I really appreciate the wavelength flexibility of their FROG systems so that measurements can be performed in different wavelength domains using a single system. Special efforts were made to find the best solution for my needs and to optimize the system’s performance. The FROG software is very advanced and allows a detailed analysis of the measurement data. Finally, I also really value the fast response I receive from Femto Easy customer support in case of questions.
Valentin MaffeisLaser process R&D Engineer - HEF Groupe - France
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.
Karolis BalskusSenior Laser Engineer - Menhir Photonics - Switzerland
Menhir Photonics AG acquired a versatile Femto Easy multi-shot autocorrelator MS-ROC some time ago. This tool has been essential for accurate pulse duration measurements for multiple R&D projects. This version of the MS-ROC covers pulse durations from 50 fs to 40 ps. It is perfect for our high repetition rate, low pulse energy lasers.
