摘要: 本文基于二阶微扰理论研究频域中强线性啁啾飞秒脉冲作用下双光子过程。详细分析了频域中啁啾因子、中心波长等参数对双光子跃迁的影响。阐明了弱场产生的双光子跃迁在频域的动态演化过程。进一步利用拓展的四阶微扰理论研究了中强场条件下双光子吸收过程的物理机理。相比复杂而昂贵的脉冲整形而言，本文提出的研究方案具有简单、经济且易操作的优势。
Abstract: Based on second-order perturbation theory, we study two-photon transition under an intermedi-ate-strong linearly chirped pulse. We analyze the effects of chirp parameter, central wavelength and pulse width on two-photon transition in detail. We show the dynamic evolution of two-photon transition probability in frequency-domain. We additionally study two-photon absorption under intermediate-strong linearly chirped pulse. Compared with common scheme with pulse shaping, the proposed scheme has advantages, such as simplicity, economy and easy operation.
