【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.更多还原
