We observed a propagating femtosecond light pulse train generated by an integrated array illuminator as a spatially and temporally continuous motion picture. To observe the light pulse train propagating in air, light-in-flight holography is applied. The integrated array illuminator is an optical device for generating an ultrashort light pulse train from a single ultrashort pulse. The experimentally obtained pulse width and pulse interval were 130 fs and 19.7 ps, respectively. A back-propagating femtosecond light pulse train, which is the -2 order diffracted light pulse from the array illuminator and which is difficult to observe using conventional methods, was observed.
我们将集成阵列照明器产生的飞秒光脉冲序列视为时空连续的动态图像进行观察。为了观察在空气中传播的光脉冲序列，采用了飞行中光全息术。集成阵列照明器是一种用于从单个超短脉冲产生超短光脉冲序列的光学装置。实验测得的脉冲宽度和脉冲间隔分别为130飞秒和19.7皮秒。我们观察到了一个反向传播的飞秒光脉冲序列，它是阵列照明器的 -2 级衍射光脉冲，用传统方法很难观察到。
