我们演示了一种以飞秒时间分辨率获取单次泵浦探测数据的方案。从 100 微米厚的染料溶液记录的数据表明,使用 70 飞秒激光脉冲可以轻松实现脉冲长度限制的分辨率。这项技术为研究各种固体中的不可逆超快过程打开了大门。此外,与传统技术不同的是,在该方法中,多次发射数据不受逐次激光强度波动的影响。
We demonstrate a scheme for taking single-shot pump-probe data with femtosecond time resolution. Data recorded from a 100-microm-thick dye solution show that pulse-length-limited resolution can be achieved readily with 70-fs laser pulses. This technique opens the door for the study of irreversible ultrafast processes in a wide variety of solids. Also, unlike with conventional techniques, in this method multiple-shot data are not affected by shot-to-shot laser intensity fluctuations.
