我们展示了一种新颖的飞秒矢量场合成器的设计。通过在调制器的分开的半部分中调制两个横向偏振分量的幅度和相位，在零色散压缩器中利用单个1D双层空间光调制器来实现电场的所有四个自由度（幅度、相位、椭圆率和取向角）的脉冲成形。作为一种共光路安排，它在干涉测量上是稳定的，因此可用于长期测量。该方法在相干控制和非线性光谱学中有着广泛的应用。
We demonstrate a novel design for a femtosecond vector field synthesizer. Pulse shaping of all four degrees of freedom of the electric field (amplitude, phase, ellipticity, and orientation angle) is achieved with a single 1D double-layer spatial light modulator in a zero-dispersion compressor by modulating the amplitude and phase of the two transverse polarization components in separate halves of the modulator. Being a common-path arrangement, it is interferometrically stable and therefore usable for long-term measurements. The method can be broadly applied in coherent control and nonlinear spectroscopy.
