摘　　要：We report on the generation of a high energy and long pulse for pumping optical parametric chirped-pulse amplification （OPCPA） by a high-birefringence photonic crystal fibre （HB-PCF） and a laser-diode-pumped regenerative chirped pulse amplifier. Using the femtosecond pump pulse centred at 815 nm, a 1064 nm soliton pulse is produced in the HB-PCF. After injecting it into an Nd：YAG regenerative amplifier with the glass etalons, a narrow-band amplified pulse with an energy of -4 mJ and a duration of 235 ps is achieved at a repetition rate of 10 Hz, which is suitable for being used as a pump source in the 800 nm OPCPA system.We report on the generation of a high energy and long pulse for pumping optical parametric chirped-pulse amplification （OPCPA） by a high-birefringence photonic crystal fibre （HB-PCF） and a laser-diode-pumped regenerative chirped pulse amplifier.
