Abstract :
Summary form only given: We report novel all-fiber concept based on parallel combining of multiple nanosecond pulse fiber lasers by means of fused fiber combiners. The radiation of 19 laser modules was coupled into 500 μm core delivery fiber with BPP equalled to 31.6 mm × mrad. Peak power 0.4 MW and pulse energy 40.5 mJ were achieved. Average power was 4.05 kW within 1064 nm wavelength range.
