用单次光谱干涉法测量了O2、N2、N2O和Ar对强非电离超短光抽运脉冲的绝对非线性时变响应。瞬时和延迟的旋转响应被区分为泵浦脉冲持续时间和探测中心波长的函数。我们的测量是核心的建模和理解的非线性传播的强超短激光脉冲在气体中。
The absolute time-dependent nonlinear response of O2, N2, N2O, and Ar to intense nonionizing, ultrashort optical pump pulses is measured with single-shot spectral interferometry. The instantaneous and delayed rotational responses are distinguished as a function of pump-pulse duration and probe central wavelength. Our measurements are central to the modeling and understanding of nonlinear propagation of intense ultrashort laser pulses in gases.
