A new World record for BIVOJ laser

The BIVOJ laser has broken its own performance record that is 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.

A team of scientists from the High Energy Slab Lasers group, led by Dr. Martin Divoký at HiLASE Centre, managed to significantly improve the world record of average power output from a high energy laser on 26 January 2021. This achievement was accomplished in cooperation with British partners from the Science and Technology Facilities Council’s (STFC) Central Laser Facility. The project is jointly funded by the H2020 “Widespread Teaming” programme and the Ministry of Education, Youth and Sports of the Czech Republic.

The BIVOJ laser system, a pulsed nanosecond diode-pumped solid-state laser, developed at STFC’s Central Laser Facility, classifies as a powerful kW laser and utilizes a cryogenic cooling technology to achieve high average power output. At the end of 2016, the Czech-British team of scientists amplified laser pulses, with a pulse duration of 10 ns, a wavelength of 1030 nm to an energy of 105 J at a repetition rate of 10 Hz, thus setting a world record for the first kilowatt laser source in a given class of high-energy lasers, which has not been surpassed yet, until now.

Now, four years later, the record from 2016 was surpassed by almost 40%, reaching maximum output energy of 146.5 J in 10 ns pulses with a repetition rate of 10 Hz at a wavelength of 1030 nm.
