The BIVOJ laser has broken its own performance record that it set in 2016. In a recent test, the system was operated for an hour at a pulse energy in excess of 145 J (with a maximum of 146.5 J) in 10 ns pulses at a repetition rate of 10 Hz at a wavelength of 1030 nm.
The Minister of Education, Youth and Sports Robert Plaga, President of the Czech Academy of Sciences Eva Zažímalová, and Director of the Institute of Physics of the Czech Academy of Sciences Michael Prouza signed the memorandum of cooperation on the membership of the Czech Republic in the legal entity of ELI ERIC.
Researchers from the Institute of Physics of the Czech Academy of Sciences and Charles University have just published in Nature Electronics their new experiment in which they succeeded to write information into an antiferromagnet by femtosecond-laser pulses.
The “red giants” are an interesting type of huge and bright stars for astronomers. They are considered old even from the cosmic perspective as they have been evolving over a long period of time. Surprisingly, there is only a few of them in the region near the centre of our Galaxy, where an increased presence of younger stars has been revealed instead. A study, proposing a process to explain this anomaly, co-authored by the researchers from the Czech Academy of Sciences, has been published by The Astrophysical Journal.
