the theoretical analysis of a q-switched fiber laser and experimental study on the self-q-switched phenomenon of an erbium-doped fiber laser are conducted 对光纤激光器中的自调q进行了实验研究,观测到了高掺铒光纤激光器中的自调q现象。
based on the transferred-electron theory of the iii-v compound semiconductor and the research on the lock-on effect of the si-gaas pcss's, this paper proposes the monopole charge domain model similar to the guun or high-field domain to explain the peculiar switching phenomena occurring in the lock-on mode theoretically 本文基于gaas等?族化合物半导体的转移电子理论,结合半绝缘gaas光电导开关中特有的lock-on效应的研究,提出了类似于耿畴(高场畴或偶极畴)的单极电荷畴理论模型,对光电导开关lock-on效应的各种现象给出了理论解释。
plasma erosion opening switch ( peos ) is a critical device used in the pulsed power apparatus for modern radiation physics and inertial confinement fusion research . there is no perfect theoretical description or model for pegs presently, and the switching phenomena differ from system to system . in addition, there is still much to do for the improvement of performance 等离子体融断开关(peos)是现代辐射物理和惯性约束聚变等研究领域中脉冲功率技术的关键部件之一,其工作机理目前尚无完善的理论解释和物理模型描述,实验现象因装置的多样性而差别较大,开关性能则有待进一步的提高。
