Nobel Prize Gérard Mourou visits FCUP and Sphere Ultrafast Photonics

Nobel Prize Gérard Mourou visits FCUP and Sphere Ultrafast Photonics Last Friday, April 26, Prof. Gérard Mourou, one of the laureates of the Nobel Prize in Physics 2018, visited our research group and laboratories at the Department of Physics and Astronomy (FCUP), as well as Sphere Ultrafast Photonics, our deep-tech spin-off company. His talk on the present and future role of ultra-intense lasers was truly inspiring (the conference hall was packed) - "The best is yet to come!". A truly great and memorable day for everyone: young students, researchers, professors, and the general public.

Prof. Marcelo Rebelo de Sousa, the President of the Portuguese Republic, visits Sphere Ultrafast Photonics

Prof. Marcelo Rebelo de Sousa, the President of the Portuguese Republic, visits Sphere Ultrafast Photonics 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.Bottom picture - from left to right: João Matos (CEO, 2bpartner), José Teixeira (CEO, DST group), Helder Crespo (CTO, Sphere Ultrafast Photonics), Marcelo Rebelo de Sousa (President of the Portuguese Republic), and Rosa Romero (CEO, Sphere Ultrafast Photonics).

d•scan in its natural habitat!!

d•scan in its natural habitat!! 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!

Ultrafast Phenomena 2016

Ultrafast Phenomena 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.

<2.5 fs - the shortest light pulse in the world directly from a single channel compressor!

<2.5 fs - the shortest light pulse in the world directly from a single channel compressor! 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.

Sphere Photonics awarded as “Most Promising Technology”

Sphere Photonics awarded as "Most Promising Technology" Sphere Ultrafast Photonics, was awarded last Friday 27 November the “Most Promising Technology” prize within the UP Awards 2015, organised by Portugal Startups!The UP Awards Gala took place at the “Pavilhão do Conhecimento Ciência Viva” (Pavillion of Knowledge Ciência Viva) in Lisbon. This is an event for gathering the whole entrepreneurial ecosystem, and to showcase some of the best work done in Portugal, from Startups to Organizations and remarkable people within this community. More than 300 representatives from start-ups and spin-offs from all over mainland Portugal and the Islands attended the Gala, as well as important economical players in Portugal, such as Microsoft, Sage, and others, and the President of the Lisbon City Council. Sphere Ultrafast Photonics was represented by two of their founders, Helder Crespo and Rosa Romero, who received the award on behalf of the Sphere team: http://portugalstartups.com/2015/11/and-the-2015-up-awards-winners-are/ Sphere Photonics already received the first prize of the New Business Ideas Competition of the University of Porto (iUP25k) in 2013, and counts with the support of the venture capital company 2bpartner (http://www.2bpartner.com), which at this event was also awarded in the category of “Investment Firm of the Year 2015”, having competed with two other finalists, Portugal Ventures and Caixa Capital. Sphere was distinguished by its innovative laser technology that allows for the generation, control and measurement of laser pulses with unprecedented pulse durations, down to 3 femtoseconds (1 femtosecond = 0,000 000 000 000 001 seconds), which are among the shortest events ever produced and measured. The customers of Sphere Photonics include some of the most prestigious universities in the World, such as Berkeley University (California, USA) and École Polytechnique (France). Sphere Ultrafast Photonics has its origin in the Department of Physics and Astronomy of the Faculty of Sciences of the University of Porto (http://dfa.fc.up.pt) and its research Institute IFIMUP (http://www.ifimup.up.pt/research/groups/ultrafast), in partnership with Lund University in Sweden (http://www.atomic.physics.lu.se/research/attosecond-physics/)
