In HiLASE Centre, a new generation of diode-pumped lasers with high average power and high repetition frequency has been developed for a long time. We talked to Jan Brajer, a leading expert from the HiLASE Centre, about colours of the laser as well as success in laser shock peening.
The HiLASE Centre in Dolní Břežany is celebrating another success; another world record. At the end of January, the High Energy Slab Lasers scientific team managed to break their own world record on the BIVOJ laser system by 40%. Converting to the second harmonic frequency, they demonstrated 515 nm, second harmonic pulses with an energy of 95 J at a repetition rate of 10 Hz.
We are happy to announce that the BIVOJ laser system is once again a record holder in its performance class. This is BIVOJ's second world record this year and the third overall. Earlier this month the high energy output from BIVOJ was converted (via second harmonic frequency conversion) to 515 nm wavelength pulses with an energy of more than 68 J at a repetition rate of 10 Hz, which at the time of writing is the world's highest average power in the category of high energy (>1 J), high average power lasers.
This year marks a decade since the European Commission and the Czech Ministry of Education, Youth and Sports approved two unique laser research projects ELI Beamlines and HiLASE, which were both successfully implemented as part of the Institute of Physics of the Czech Academy of Sciences. In celebration of the anniversary, an official meeting attended by the representatives of leading Czech and foreign institutions took place at ELI Beamlines in Dolní Břežany. In a video-call, it was also joined on-line by Gérard Mourou, the winner of the Nobel Prize for Physics and the initiator of the centre at the European level.
The new record in multibeam laser nanostructuring, with respect to the number of laser beams simultaneously modifying the material surface, was reached due to the active scientific cooperation of HiLASE Centre with the Israeli company HOLO/OR Ltd.
HiLASE Centre as a part of the Institute of Physics of the CAS has achieved another world record. The Laser Micromachining team led by Peter Hauschwitz, applied a concept of multi beam processing of record speed of 1909 cm2/min to create nanostructures on stainless steel.
Innovative methods of material surface treatment and a completely new and unique solution in the field of industrial tool preparation, using laser technologies, are available thanks to Hi-Beams, s.r.o., a newly established spin-off of HiLASE Centre and SHM company, an expert on industrial PVD coatings.
The BIVOJ laser has broken its own performance record that it set in 2016.
Petr Hauschwitz from HiLASE Centre has now made it into the prestigious 30 UNDER 30 list in the Czech version of the FORBES magazine
