Short pulse laser radiation can be used to ionize atoms / molecules as well as excite specific atomic/molecular states. For longer laser pulses (duration of many optical cycles) the process depends basically on the wavelength, polarization and intensity. For pulse duration as short as a few optical cycles, the carrier envelope phase (CEP) is an important parameter for such processes. The CEP is defined as the phase of the electric field at the peak with respect to the maximum of its pulse envelope.

短脉冲激光辐射可用于电离原子/分子以及激发特定的原子/分子态。对于较长的激光脉冲(许多光周期的持续时间)，这一过程基本上取决于波长、偏振和强度。对于短至几个光周期的脉冲，载波包络相位(CEP)是这类过程的一个重要参数。CEP被定义为峰值电场相对于其脉冲包络的最大值的相位。
