We report on the development of highly dispersive mirrors for chirped-pulse oscillators (CPOs) and amplifiers (CPAs). Low-loss and alignment-insensitive all-dispersive-mirror compressors can take over the role of prisms and gratings in conventional CPA systems, with the added benefit of shorter pulse duration due to high-order dispersion control and absence of self-phase modulation. The evolution of dispersive dielectric multilayer mirror technology within the last 15 years now allows us to report a new generation of low-loss and alignment-insensitive high-dispersion mirrors (HDMs). In this proof-of-concept study, we demonstrate the usability of highly dispersive multilayer mirrors for high-energy femtosecond oscillators, namely for a chirped-pulse Ti:Sa oscillator and an Yb:YAG disk oscillator. In both cases, a group delay dispersion (GDD) in the order of 2×10

针对压电快速倾斜镜的反作用力对有效光学元件的复杂动态耦合干扰问题,提出了基于多体系统的刚柔耦合和基于压电耦合理论的反作用力分析方法,对压电倾斜镜的反作用力进行了分析和补偿,并获取了中心柔性铰链的热点应力。理论和实验结果表明:压电耦合求解相比于多体系统的刚柔耦合方法更能准确地反映反作用力特性,实验测得反作用力的补偿比例可以达到90.14%,与数值计算的差异为3.96个百分点。所提的反作用力分析方法和动量补偿结构可为计算和消除倾斜镜的反作用力对光学系统的耦合干扰提供借鉴。
