我们首次利用全息光在飞行中记录技术，成功地记录和观测了可见飞秒光脉冲在空间和时间上的连续运动图像。我们将二次谐波产生（SHG）应用于锁模钛蓝宝石激光器的近红外飞秒光脉冲，以产生可见飞秒光脉冲。产生的光脉冲的中心波长为400 nm，持续时间为100 fs左右。我们获得了在漫射板上以145 ps的速度传播的可见光和准直飞秒光脉冲的动态图像。(C) 2011日本应用物理学会
We succeeded in recording and observing a spatially and temporally continuous moving picture of visible femtosecond light pulse propagation by using light-in-flight recording by holography, for the first time. We applied second-harmonic generation (SHG) to a NIR femtosecond light pulse from a mode-locked Ti:sapphire laser to generate a visible femtosecond light pulse. The center wavelength and duration of the generated light pulse were 400 nm and similar to 100 fs, respectively. We acquired a moving picture of a visible and collimated femtosecond light pulse that propagated on a diffuser plate for 145 ps. (C) 2011 The Japan Society of Applied Physics
