通过对频域干涉原理的深入研究,本文提出了一种超快时间分辨力的脉冲激光频域干涉技术.采用该技术方法可精确同步泵浦-探测实验中泵浦脉冲和探测脉冲的传输时间,其同步精度与脉冲激光器脉宽相当.本文详细论述了频域干涉技术的系统构成和工作原理,数值模拟了飞秒脉冲激光频域干涉仪的输出信号,指出当频域干涉仪输出的条纹数最少时,两脉冲之间的传输时间差即达到最小,最后通过动态实验验证了理论推导结果.

On the basis of careful investigation for the frequency-domain interference, a new technology named pulse frequency-domain interferometry is illustrated. By means of the new technology, the pump pulse and probe pulse can arrive at the measured target synchronously in the pump-probe experiments. The time resolution of frequency-domain interferometry is more than the pulse period. The work principle and system structure are illustrated in detail. After simulating the output signal of frequency-domain interferometry in theory, it comes to a conclusion that the pump pulse and probe pulse have arrived at measured target synchronously when only one output stripe appears in frequency-domain interferometry. Further dynamic experiments draw the same result as is shown in theoretic simulation.
