Femto Easy is a company specialized in ultrafast metrology. Our company is a spin-off from the CELIA laboratory in Bordeaux, France, which has a strong expertise in the production and characterization of high energy ultrashort pulses. We provide robust and reliable measurement devices for ultrafast lasers, already used in some state of the art laboratories.
Our current product-line includes a single shot autocorrelator, capable of measuring few cycle pulses with interferometric resolution, and an innovative SHG single shot FROG. Both are suitable for several wavelength ranges (from UV to mid-IR) and several pulse durations, down to 5 fs.
Beside their intrinsic technical performances, our products are very easy to use, compact, portable and versatile, which make them the ideal tools for customer services. The products are associated with a high quality user-friendly software which contributes to make them easy and pleasant to use. We also make vacuum compatible measurement devices and custom products upon request and we provide our expertise on ultrafast metrology.
Reasons to use Femto Easy products
The ROC autocorrelators are ultra compact and robust single shot autocorrelators. As the name implies, they are designed specifically to be ultra easy to use and to align onto the laser beam. They cannot be misaligned, there is no need for calibration or tweaking and they are easily transportable. And yes, they are rock-solid!
Besides those advantages, the ROCs autocorrelators provide excellent technical performances and highly accurate measurements.
The ROCs autocorrelators are available for several wavelength and several pulse duration.

Measurement of few cycle pulses
On the top, the raw image of the spatially resolved autocorrelation trace.
At the bottom, the analysed autocorrelation trace integrated over the spatial coordinate. The experimental data (in red) are fitted by a Gaussian function (in blue). The full width at half maximum of the autocorrelation trace is 8.3 fs. The corresponding Gaussian pulse duration is 5.9 fs.
Measurement of low energy pulses
The average power used for the measurement was with only 20 mW at 62 MHz repetition rate. It means that in this conditions 0.3 nJ per pulse was enough to get a clean measurement. At the buttom, the raw image of the spatially resolved autocorrelation trace.
On the top, the analysed autocorrelation trace integrated over the spatial coordinate. The experimental data (in blue) are fitted by a Gaussian function (in red). The full width at half maximum of the autocorrelation trace is 30.4 fs for a Gaussian pulse duration of 21.5 fs.
GigaHertz / low energy (pJ) measurement
The measured laser was a SESAM modelocked VECSEL developed at ETH Zurich1, assembled, amplified and CEO stabilized at the University of Neuchatel2.
This was the very first measurement of a GHz rep. rate Laser with a single shot device.
