The BIVOJ laser system is a kW-class nanosecond pulsed diode pumped solid state laser (DPSSL). First operation of the laser at the end of 2016 demonstrated amplification of 10 ns pulses at 10 Hz pulse repetition rate to the energy of 105 J at 1029.5 nm, representing the world’s first kW average power, high-energy, nanosecond pulsed DPSSL. In 2021, Bivoj broke his own record by reaching over 145 J – read more. The name “Bivoj” was chosen in a reader’s poll of the magazine Vesmír and it reminds of the mythical Czech strongman.
