准参量啁啾脉冲放大（QPCPA）是一种通过耗尽闲频脉冲实现啁啾信号脉冲放大而无需后转换的新方案。在本文中，我们提出了一个数值研究的带宽，效率和鲁棒性的QPCPA。相互作用波之间的自锁相位被认为是抑制反向转换的根本机制，这使得即使在相位失配条件下，信号效率也接近量子极限，从而大大提高了QPCPA的相位失配容限。我们表明，QPCPA可以突破传统的光参量放大中遇到的效率和带宽之间的权衡，从而支持高效的放大的几个周期的脉冲。(C)2017美国光学学会
Quasi-parametric chirped pulse amplification (QPCPA) is a new scheme that enables the amplification of chirped signal pulses without back conversion by depleting the idler pulses. In this paper, we present a numerical study on the bandwidth, efficiency, and robustness of QPCPA. Self-locked phase among the interacting waves is found to be the underlying mechanism for the suppression of back conversion, which allows signal efficiency approaching to the quantum limit even under the phase-mismatch condition, and thus greatly increases the phase-mismatch tolerance of QPCPA. We demonstrate that QPCPA can break through the trade-off between the efficiency and bandwidth encountered in conventional optical parametric amplification, hence supporting highly efficient amplification of few-cycle pulses.
