RP 2: Development of high-energy class diode-pumped solid-state lasers and associated technologies

The main objective of the Research Program 2 is the development of high-energy class diode-pumped solid-state lasers. First operation of the multi-slab laser at HiLASE (“Bivoj”) at the end of 2016 demonstrated amplification of 10 ns pulses at 10 Hz pulse repetition rate to an energy of 105 J at 1029.5 nm, representing the world’s first kW average power, high-energy, nanosecond pulsed diode pumped solid state laser. We also work on associated laser technologies, which include high-power optical isolators, adaptive optics, and characterization of laser materials at cryogenic temperatures.

Efficient, high energy, pulsed laser systems operating at high pulse repetition rates (10 Hz and beyond) are required for a wide range of commercial and scientific applications, including advanced materials processing, laser shock treatment of mechanical components, and pumping of ultra-high intensity fs petawatt-class lasers to generate high-brightness secondary radiation (x-ray, gamma-ray) and particle (electron, proton, ion, muon) sources. These have potential applications for novel medical therapies, and in high-resolution radiography and advanced imaging for industrial and security sectors.

Antonio Lucianetti, RP2 leader: Putting curiosity to the use of society

Antonio Lucianetti received his Ph.D. in physics from University of Bern, Switzerland, in 1999. His research interests include high-energy cryogenic short pulse lasers, microchip lasers, high-energy optical isolators, laser-driven particle and radiation sources, and laser-based interferometric gravitational wave detectors. In 2017 he was awarded habilitation by the Italian Ministry of Education, University, and Research for full professor in the scientific sector ‘Experimental Matter Physics’. In the same year, he became a visiting Professor, National Institutes of National Sciences, National Institute for Fusion Sciences, Toki, Japan. He has authored/coauthored more than 135 journal articles and conference papers, with more than 4000 citations.
