摘要：

A 2.5 mum thick corona poled copolymer film was used to double approximately 13 fs long, 50 nJ energy, 625 nm wavelength pulses at 8 KHz repetition rate. The large effective d coefficient results in a relatively high conversion efficiency for such a thin film. A maximum efficiency of 0.13% has been measured. Long term stable operation was obtained with efficiencies of 0.025% at the damage threshold of approximately 160 GW/cm2. The damage threshold is remarkably high for organic materials, and was found to be peak intensity rather than average intensity dependent.
