Because maximal total light absorption corresponds to a pulse, the pulse oximeter also provides a figure for pulse rate.
因为最大的总光吸收与脉搏相对应，因此脉博血氧测定仪也提供了脉率的图形。

The expression of two-photon absorption probability for the decaying optical pulse series excitation is given and a simple experimental method is suggested.
给出了衰减多脉冲光激发的双光子吸收几率的表达式。 提出了一种简单易行的实验方案。

In this paper, we got the regularity of cavity ring-down spectroscopy when the line width of laser pulse is far larger than the absorption line width of measured substance.
