The public summary of the project has been published on the EU server CORDIS.
The link is also available in the menu bar of the website, in the section “Publications”.

After having reported these results in international conferences (AES 2017 South Korea, COLA 2017 France, Ultrafast Optics 2017 Moscow), having been published in Czech public media (Novinky.cz, Technical Weekly CZ, Ceske Televize 24), it was time to report this success story at the HiLASE Centre (FZU Prague). The seminar duration was 45 minutes and the time was shared between T.J.-Y. Derrien, Y. Levy and I. Mirza.

Seminar abstract is available on the HiLASE website: PDF.

In line with the WP 3 of the Marie Curie project QuantumLaP, T. J.-Y. Derrien is joining the group of Prof. Angel Rubio from March 1st 2018 to develop further the quantum theory of laser-matter interaction. He will be spending 70% of his time in the Theory Group of Max Planck Institute for Structure and Dynamics of Matter (Hamburg) and supporting the HiLASE (Prague) activities by 30% of the time.

Dr T. J.-Y. Derrrien has been invited by Bochum University (Germany) to provide 30 hours of lectures on the topic of Plasmonics, as a block-lecture course for the Erasmus Mundus Master program named “Laser Technologies and Photonics.” A written exam is planned in early March and about 10 people are expected.

14th November 2017 Technical Weekly, Prague.

This Tuesday 14th of November 2017, several articles were published in the media of Czech Republic on our research findings.

1. An interview of Prof. N. M. Bulgakova and Dr. T. Derrien has been published in Technical Weekly on the 14th of November 2017. This public review aims to inform citizens of Czech Republic on the latest public news about research and technology. It is mostly read by people from research and industry. A snapshot of the printed article is provided. The website only provides the first sentences of the article.
2. The same interview has also generated a second full length article (in Czech) available on the website of Czech Television (Ceska Televize), the most important public funded channel in the Czech Republic. The Google Translation though reveals some inaccuracies, which could emerge from the automatic translation. As we didn’t get the chance to authorize the final version of the article, a list of inaccuracies is provided below.
3. The news was also republished by Novinky.cz, 7th-8th most visited website in the Czech Republic (according to Alexa).
4. Finally HiLASE also republished the article in Czech (link to the article) on the laboratory web page.

List of mistakes identified in the article of Czech Television.

• The original discovery of the large area processing at such level of regularity was demonstrated by the group of Jan Siegel and Javier Solis in CSIC Madrid, Spain (Optics Letters 2014). The limit of this study was found in the treated material: only Chromium could exhibit regular structures in the regime of removing matter with laser (named “ablation regime”).
• The novelty of our study lies in the theoretical model, which predicts the possibility to obtain high regularity on a large amount of metals as the experimentally observed regularity was successfully correlated with the distance on which some surface electromagnetic waves travel at the surface of the laser-irradiated metal.
• The contribution from our italian colleagues is found in the realization of the series of experiments performed on 6 metals, which support the theoretical analysis and theoretical predictions.
• The head of HiLASE is Dr. Tomas Mocek (see the page of staff on HiLASE website). Note that this mistake was introduced by Google Translate, and not by the authors.

We are happy to announce that our Marie Curie (H2020, EU) project “QuantumLaP” has now reached its maturity. The final report of the Marie Curie funding has been submitted on the 31st of October, after 2 years of great support from Marie Skolodowska Curie Actions for a total of 147,000 € over 2 years.

Nobel Prize laureates who have worked in Lebedev Institute, Moscow.

I was honoured to give an invited oral presentation (30 min) at the Ultrafast Optics conference held at the Lebedev Institute, Moscow. The audience at this conference was truly exceptional. The impact of the talk was excellent and the questions from the audience were very constructive. Many thanks to Prof. Uryupin and to Prof. Kudryashov for the organization.

We are happy to announce the publication of our manuscript entitled “High-speed manufacturing of highly regular laser-induced periodic surface structures on metals: physical origin of the regularity.” to the journal Scientific Reports of the Nature Publishing Group.

In the paper, we at HiLASE developed the theory of surface plasmon polaritons for materials irradiated by intense laser light, and our co-authors in University of Modena (Italy) prepared laser-induced periodic surface structures at high throughput, competitive with other existing methods of lithography. Novelty of the study lies in the accuracy of the description that could be made a large range of materials, where the laser-induced nanostructures will be highly regular for developing nanostructure demanding applications. The study also reveals that reducing the wavelength of the laser may improve the regularity for seemingly any material. We hope this paper will help the large community of scientists and engineers working in this field to reach a better control of their laser-induced nanostructures in future.

Official press release: http://www.hilase.cz/en/thibault-derrien-and-yoann-levy-published-in-scientific-reports/

Our latest paper on the mechanisms of highly regular laser nanostructuring was presented at the Advanced Electromagnetics Symposium (AES), Incheon, close to Seoul, South Korea.

A new publication has been released in SPIE Proceedings. It presents a large scale model of ultrashort laser modification of semiconductors that was developed at Hilase to predict the changes of silicon material upon intense pulsed laser irradiation. A more complete publication aiming to demonstrate the level of prediction we have reached is under preparation.
