Pulsed excitation fields are routinely used in most laser and nuclear magnetic resonance (NMR) experiments. In the NMR case, constant amplitude (rectangular) pulses have traditionally been used; in laser spectroscopy the exact pulse shape is often unknown or changes from shot to shot. This article is an overview of the effects of radio-frequency and laser pulse shapes and the instrumental requirements for pulse shaping. NMR applications to selective excitation, solvent suppression, elimination of phase roll, and reduced power dissipation are discussed, as are optical applications to soliton generation, velocity selective excitation, and quantitative population transfer.
脉冲激发场在大多数激光和核磁共振（NMR）实验中经常使用。在核磁共振的情况下，传统上使用恒定幅度（矩形）脉冲；在激光光谱学中，确切的脉冲形状通常未知或每次测量都会变化。本文概述了射频和激光脉冲形状的影响以及脉冲整形的仪器要求。讨论了核磁共振在选择性激发、溶剂抑制、消除相位滚动和降低功耗方面的应用，以及光学在孤子产生、速度选择性激发和定量粒子转移方面的应用。
