我们使用声光调制器(AOM)实现了中心波长为795 nm的高分辨率放大脉冲整形。输出脉冲的能量为200微焦耳/脉冲，变换极限脉冲宽度为150fS。在单个脉冲中实现了超过40个特征的光谱调制。我们使用Struts(光谱和时间分辨上转换技术)来表征脉冲。利用预失真技术，我们证明了脉冲可以在幅度和相位上进行整形。我们产生了具有双曲正切振幅和双曲正切频率扫描的复杂脉冲波形，这对于绝热快速通过实验是有用的。(C)1998年美国光学学会
We demonstrate high-resolution amplified pulse shaping using an acousto-optic modulator (AOM) at a center-wavelength of 795nm. The output pulses have energy of 200 mu J/pulse and a transform-limited pulsewidth of 150fs. A spectral modulation of over 40 features is achieved in a single pulse. We characterize the pulses using the STRUT (Spectrally and Temporally Resolved Upconversion Technique). Using predistortion techniques, we demonstrate that the pulses can be shaped in amplitude and phase. We create a complex pulse shape with hyperbolic secant amplitude and hyperbolic tangent frequency sweep, which is useful for applications in adiabatic rapid passage experiments.
