Abstract

Steady-state chirped-pulse amplification was applied to a five-stage dye amplifier system to extract available energy over the full gain duration and at the same time suppress the amplified spontaneous emission (ASE). An output energy of 41 mJ was generated with 1.4-ns chirped pulses having an ASE of 3% and a pumping efficiency of 8.8% for the final amplifier. After five-stage amplification these pulses were compressed to 320 fs FWHM.
