Read a paper co-authored by HiLASIANS regarding the construction and operation of the KAZI laser<\/a>, developed in collaboration between HiLASE Centre and the CALTA team at the Central Laser Facility<\/a> of the Science and Technology Facilities Council (STFC).<\/p>\n

\"\"<\/p>\n

The paper describing its operation is titled Demonstration of stable, long-term operation of a nanosecond pulsed DPSSL at 10 J, 100 Hz<\/a> <\/em><\/strong>and was published in the Optics Express<\/a><\/em> journal. As co-authors, Martin Divok\u00fd (team leader of High Energy Slab Lasers), Jan Pila\u0159 (senior researcher), Ond\u0159ej Denk (optical engineer), and Tom\u00e1\u0161 Mocek (head of HiLASE Centre) are joined by a group of researchers from STFC: Mariastefania De Vido, Gary Quinn, Danielle Clarke, Luke McHugh, Paul Mason, Jacob Spear, Jodie M. Smith, Thomas J. Butcher, Chris Edwards, and John L. Collier.<\/p>\n

We report on stable, long-term operation of a diode-pumped solid-state laser (DPSSL) amplifying 15 ns pulses at 1029.5 nm wavelength to 10 J energy at 100 Hz pulse rate, corresponding to 1 kW average power, with 25.4% optical-to-optical efficiency. The laser was operated at this level for over 45 minutes (\u223c3\u2009\u00b7\u2009105 shots) in two separate runs with a rms energy stability of 1%. The laser was also operated at 7 J, 100 Hz for 4 hours (1.44\u2009\u00b7\u2009106 shots) with a rms long-term energy stability of 1% and no need for user intervention. To the best of our knowledge, this is the first time that long-term reliable amplification of a kW-class high energy nanosecond pulsed DPSSL at 100 Hz has been demonstrated.<\/em><\/p>\n

Furthermore, the paper concludes that with a room-temperature booster pre-amplifier (PA2) in the front-end section, increased efficiency and higher polarization purity can be achieved in the future. In addition, the quality of the near-field profile is also expected to improve with further adjustments, leading to expected future output energy above 10 J. Lastly, scalability of pulse rate beyond 100 Hz is a subject of ongoing research.<\/p>\n
