摘要: 研究了简并四波混频(DFWM)的时间分辨曲线,数值模拟了由延迟时间引起的两种不同光栅的时间分辨曲线以及曲线的约化半宽度与约化弛豫时间tr/tp的变化关系。Abstract: The time resolution curve (TRC) of ultrashort pulse DFWM is studied theoretically.Using Guassian shaped pulse,the time resolution curves of two types of grating are calculated respectively and their influences in measurement are discussed.
