论文摘要
该论文在混合Mid-Ir搅动的脉冲振荡器 - 放大器(CPO-CPA)系统中引入了一条新的途径,直达超快速激光峰值和能量缩放系统,而不会牺牲脉冲持续时间也没有牺牲脉冲持续时间。该方法基于使用CPO作为种子来源,允许实施耗散孤子(DS)能量缩放方法,并与通用CPA技术相结合。关键是通过使用CPO的the鼠高保真脉冲在放大器和压缩机元素的最后阶段避免具有破坏性的非线性。我们的主要目的是在基于CR2+:基于ZnS的CPO中实现这种方法,作为具有良好控制相位特征的能量量表DS的来源,用于单个PASS CR2+:ZnS放大器。实验和理论结果的定性比较为混合CPO-CPA激光系统的开发和能量缩放提供了路线图,而不会损害脉冲持续时间。建议的技术为多通CPO-CPA激光系统提供了极度强烈的超短脉冲和频率梳的途径,对于中IR光谱中的现实生活中的应用特别有趣,在1至20 um中。
The paper introduces a new route towards the ultrafast high laser peak power and energy scaling in a hybrid mid-IR chirped pulse oscillator-amplifier (CPO-CPA) system, without sacrificing neither the pulse duration nor energy. The method is based on using a CPO as a seed source allowing the beneficial implementation of a dissipative soliton (DS) energy scaling approach, coupled with a universal CPA technique. The key is avoiding a destructive nonlinearity in the final stages of an amplifier and compressor elements by using a chirped high-fidelity pulse from CPO. Our main intention is to realize this approach in a Cr2+:ZnS-based CPO as a source of energy-scalable DSs with well-controllable phase characteristics for a single-pass Cr2+:ZnS amplifier. A qualitative comparison of experimental and theoretical results provides a road map for the development and energy scaling of the hybrid CPO-CPA laser systems, without compromising pulse duration. The suggested technique opens up a route towards extremely intense ultra-short pulses and frequency combs from the multi-pass CPO-CPA laser systems that are particularly interesting for real-life applications in the mid-IR spectral range from 1 to 20 um.
