| Abstract: | A high average power linearly polarized chirped pulse amplification (CPA) system is reported, which comprises of a fully fiberized fiber amplifier chain and a transmission grating pulse compressor. Before compression, the output average power of 425 W is achieved with corresponding optical to optical efficiency of 81%, polarization extinction ratio of 13 dB and near-transform-limited beam quality. After compression, femtosecond pulses with average power of 300 W, duration of 315 fs and peak power of 12 MW are achieved. This is the highest average power ever reported in linearly polarized fiber CPA system. |
