Realtime FROG Laser Characterization
High-resolution FROG Frequency Resolved Optical Gating with visual feedback on all important pulse characteristics: pulse duration, spectral width, chirp, pulse front tilt, phase modulation, dispersion.
Frequency-Resolved Optical Gating allows for a complete recovery of pulse intensity and phase of ultrashort pulses with complex shapes. It can retrieve the full time-dependant electric field and the equivalent optical spectrum with spectral phase. In other words, FROG allows you to know the duration of your laser pulses, but also how to deal with the spectral phase to achieve the shortest possible pulse duration.

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.

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.

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.

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.
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
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. The Femto Easy team is always there for us, ready to address our inquiries and provide assistance – something we truly appreciate.
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.
