Abstract无论是在固体还是在光纤放大器中,飞秒的脉冲能量都受到热效应和非线性效应的制约。即使是啁啾脉冲放大(CPA),也难以超越高峰值功率和平均功率的限制 。脉冲空间和时间分割放大-合成,有可能打破僵局,产生高重复频率和高脉冲能量;而将高功率光纤放大器中的脉冲进行相干堆积,有可能超越啁啾脉冲放大,得 到高于其若干数量级的脉冲能量,同时保持高重复频率。
Either in the solid state or in the fiber amplifier,femtosecond pulse energy is limited by the thermal and nonlinear effects.Chirped pulse amplification(CPA)solely cannot break the barrier of high peak power and average power.Coherent pulse combination,such as the spatially or temporally divided pulse amplification,has the potential to produce higher pulse energies at high repetition rate.Furthermore,coherent pulse stacking from high repetition rate,high power fiber amplifier may even surpass the chirped pulse amplification and produce many order higher pulse energy with high repetition frequency.
