论文摘要
我们提出了一种新型的光学参数放大方案，该方案将准阶段匹配与涉及特定长度的晶体段的复合脉冲方法相结合。提出的方案高度提高了频率转化的鲁棒性，以针对非线性耦合以及泵，惰轮或信号波长的变化，因此具有增强高扩增和宽带操作的潜力。给出了应用于linbo_3的示例。
We propose a novel optical parametric amplification scheme which combines quasi-phase-matching with a composite pulse approach that involves crystal segments of specific lengths. The presented scheme highly increases the robustness of the frequency conversion against variations of the nonlinear coupling and of the pump, idler or signal wavelengths and has therefore the potential to enhance high amplification and broadband operation. Simulations examples applied to LiNbO_3 are given.
