Commissioning results of the world's first diode-pumped 10Hz PW laser

High‐Power Laser Systems

“…[ 109,110 ] In 2017, the output was improved to 97 J. [ 66 ] Further using cryogenic helium gas cooling technology, the DiPOLE laser system developed in the UK used 150 K helium to dissipate heat to the main amplifier. The laser had 105 J, 10 ns, 10 Hz, and 10.5 GW peak power with an average power of 1.05 kW.…”

“…[ 58,61,89,90 ] The multi‐slab master amplifier stage of HAPLS was jointly developed by LLNL and Lasertel; the pump system consisted of 4 LD arrays at 888 nm with peak power of 3.2 MW and pulse width 300 µs, [ 153 ] and a 97 J, 3.3 Hz laser pulse at 1053 nm has been achieved. [ 66 ] As for thin‐disk regeneration amplification, Jung et al. used a pulsed diode laser pump at 940 nm (1.7 J and 970 µs) and a 100 Hz, 1.8 ps, 240$${\rm{\;}}$$mJ pulsed light produced.…”

“…Auxiliary heat dissipation methods such as pulsed diode laser (PDL) pumping, [ 57–61 ] zero‐phonon‐line (ZPL) pumping, [ 54,62,63 ] cryogenic cooling, [ 61,64,65 ] or gas cooling [ 50,66 ] are required in addition to the basic configuration's heat dissipation benefits. Furthermore, large‐aperture crystals' amplified spontaneous emission (ASE) must be reduced by eliminating the edge oscillation conditions.…”

Development of an ultrathin liquid sheet target for laser ion acceleration at high repetition rates in the kilohertz range

“…The most recent ultrashort pulse laser systems with an average optical power of hundreds watts and better than 2% stability [1][2][3][4] have laid the technological basis for the generation of stable, user-ready, high average power secondary systems, such as X-ray and gammaray sources. One of the major challenges of the utilization of high average power lasers in plasma physics and ion acceleration is the implementation of a high repetition rate, high density target system.…”
