In recent years, size of silicon devices has been decreasing. At the present time, their size has arrived at nanometer scale, and it approximately takes several picoseconds, or even shorter time, for free carriers to transport during such small distances. Therefore, research of carrier dynamics in silicon on shorter and shorter time scale is urgently developed. Processes on such short time scale are difficultly measured by traditional electronic method, so ultrafast spectroscopy method is the only choice of carrying out such experiments. Additionally, application of photoelectric detectors is severely influenced by laser.

近年来，硅半导体器件尺寸不断变小，目前已经缩小到了纳米尺度，载流子在这个尺度内的输运时间大约在ps量级，这促使人们需要对越来越短的时间尺度内硅的载流子动力学进行研究，传统的电子学方法很难对这么短时间尺度内发生的现象进行测量，超快光谱探测几乎成了进行这类研究的唯一测试手段。
