A new standard in ultrafast laser measurements
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. We also develop a innovative compact spectrometer and beam profilers.
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 ROC autocorrelators provide excellent technical performances and highly accurate measurements.
The ROC autocorrelators are available for several wavelength and several pulse duration.
This new technique of ultrashort pulses characterization relies on interferometric single shot autocorrelation and two photon absorption. The time delay is encoded into a spatial interferogram which is used to evaluate the pulse duration, the 2ω spectrum and the chirp. There is no non-linear crystal and no phase matching issues, the spectral working range is therefore very broad (1200 - 2400 nm).
The BOAR is actually combining all the advantages : simple, extremely robust, accurate and reliable measurements, spatially resolved, suitable for rather chirped pulses and the retrieval is done in real time directly by Fourier transformation. Two models are available for two different temporal windows.
