The President of the Portuguese Republic, Prof. Marcelo Rebelo de Sousa, visited Sphere Ultrafast Photonics last Friday, October 7, as the Faculty of Science of the University of Porto (FCUP) was celebrating its 105th anniversary. The president was very interested in the developments, achievements and new products that Sphere Photonics has to offer to the World. He was also impressed by the very fast time that it takes us to bring a new product from research into the market and furthermore understood that the technologies developed at FCUP, and particularly at IFIMUP, including new methods for the measurement and control of femtosecond laser pulses down to single-cycle durations, the development of femtosecond lasers (sub-6-fs) and large-format pulsed laser holography are key examples of leading edge technology that can be found at the University of Porto. The president was accompanied by the Director of the Faculty of Science of the University of Porto, Prof. António Fernando Silva, and the Rector of the University of Porto, Prof. Sebastião Feyo de Azevedo. We also counted with the presence of our funding partners, Dr. João Matos, CEO of 2bpartner, and Eng. José Teixeira, CEO of the DST group.
A highlight of the visit was the making of a live holographic portrait of the President, thanks to the extended know-how of our CTO, Dr. Helder Crespo. This hologram of the President, one of the rare holographic portraits of a head of state while in office, will become part of the collection of the Museum of the Presidency of the Republic very soon, where it will be on display.

The laboratory is the natural habitat of the d•scan technology. Universities such us UC Berkeley and research institutes such us LOA or ELI have already adopted our technology. Everyday many ultrafast laser users have the same pain: "HOW DO I MEASURE MY FEMTOSECOND LASER SYSTEM? Everything I have tried has failed, is hard to align and use, or does not convince me in the end!”. Finally, a system that really works on the lab has appeared on the market. Do not be skeptical: Try the d•scan!

ICUIL 2016

Sphere Photonics at the 7th Conference of the International Commitee on Ultrahigh Intensity Lasers ICUIL 2016. Montebello, Québec, Canada, 11-16 September 2016.


Sphere Photonics at the International Conference on Ultrafast Phenomena 2016, where we announced the recent generation and measurement of single-cycle 2.5 fs pulses from a single-channel pulse compressor using d-scan technology. Santa Fe, USA, 17-22 July 2016.


We have successfully generated and measured the temporal profile of intense single-cycle 2.5 fs pulses, using a fully inline and collinear over-octave implementation of dispersion-scan (d-scan). We used a single-stage hollow-core fiber (HCF) compressor, pumped by sub-25 fs, 500 uJ pulses from a Ti:Sapphire CPA system (CLPU). The HCF was followed by ultra-broadband doubl- angle chirped mirrors (450-1000 nm, UltraFast Innovations GmbH), which are part of the single-cycle d-scan system (Sphere Ultrafast Photonics, SA). The spectral phase of the pulses was successfully retrieved over more than one octave using only SFG signal from 280 to 420 nm, revealing the generation of intense CEP-stable high-quality single-cycle pulses with 2.51 fs (FWHM), very close to the Fourier limit of 2.43 fs, and with a peak power of approximately 40 GW. This extreme source is highly promising for attoscience and high-field laser physics.
