We successfully demonstrate the characterization of phase- and amplitude-modulated broadband UV pulses with a shaper-assisted cross-correlation setup. A two-dimensional pulse modulator, operated in the diffractive shaping mode, is used to generate an inherently temporally overlapped reference beam. To greatly improve the usability of this method, we combined this setup with a split-mirror UV autocorrelator based on a solar-blind photomultiplier tube as sensitive nonlinearity. This allows sensitive characterization of the Fourier-limited pulses down to a few picojoules, as well as complex-shaped ultrashort UV pulses, typically occurring in coherent control experiments.
我们成功地展示了利用整形辅助的互相关装置对相位和振幅调制的宽带紫外脉冲进行特性描述。二维脉冲调制器在衍射整形模式下运行，产生固有时间重叠的参考光束。为了极大地提高该方法的可用性，我们将该装置与基于日盲光电倍增管的分束镜紫外自相关器相结合，作为敏感的非线性元件。这使得能够对低至几个皮焦耳的傅里叶极限脉冲以及相干控制实验中通常出现的复杂形状的超短紫外脉冲进行灵敏的特性描述。
