We report on the full amplitude and phase characterization of high-intensity few-cycle laser pulses generated in a single-stage hollow core fiber system with subsequent compression by ultrabroadband chirped mirrors. We use a spatially-encoded arrangement (SEA) spectral phase interferometry for direct electric field reconstruction (SPIDER) with spectral filters for ancilla generation to characterize the sub-4 fs pulses with spatial resolution.
我们报告了在单级中空芯光纤系统中产生的高强度少周期激光脉冲的全幅度和相位特性，随后通过超宽带啁啾镜进行压缩。我们使用带有光谱滤波器的空间编码相位干涉测量法（SPIDER）进行直接电场重建（SEDIR），以利用空间分辨率对亚 4 fs 脉冲进行特征化。
