摘要:

参量放大器使超快、强场和高能量密度激光科学取得了突破,并且是扩展强大的新兴二极管泵浦固体激光器技术的频率范围的重要工具。然而,由于不均匀的光提取,它们的影响受到固有的低量子效率的限制。本文提出了一种基于混合非线性光学的新型参量放大器。混合的参数放大与闲频二次谐波产生诱导不寻常的演化动力学的完全参量放大器-饱和,而不是循环增益-这里观察到的第一次。这允许高度均匀的光提取,从而使具有类高斯强度分布的无损放大器具有前所未有的效率-48 dB单级增益,68%量子效率和44%泵浦到信号能量转换-比标准提高了几倍。这种简单的方法既具有激光般的高量子效率,又具有无热负载参数系统的优点,可以广泛实施,并通过将科学和工业可用的功率增加几倍而产生重大影响。

英文摘要:

Parametric amplifiers have allowed breakthroughs in ultrafast, strong-field, and high-energy density laser science and are an essential tool for extending the frequency range of powerful emerging diode-pumped solid-state laser technology. However, their impact is limited by inherently low quantum efficiency due to nonuniform light extraction. Here we demonstrate a new type of parametric amplifier based on hybridized nonlinear optics. Hybridization of parametric amplification with idler second harmonic generation induces unusual evolution dynamics for a fully parametric amplifier - with saturating rather than cyclic gain - observed here for the first time. This allows highly uniform light extraction enabling unprecedented efficiency for a lossless amplifier with Gaussian-like intensity profiles - a 48-dB single-stage gain with 68% quantum efficiency and 44% pump-to-signal energy conversion - a several-fold improvement over the standard. Possessing both laser-like high quantum efficiency and the advantages of thermal-loading free parametric systems, this simple approach can be implemented widely and have significant impact by increasing several-fold the power available for science and industry.
