我们开发了一种新的声光可调滤波器和非机械交叉相关器的超声测量系统，该系统使用电子控制的、波长可调的飞秒孤子脉冲。在没有光学对准的情况下，可以在1.1 ~ 2.1 μm的宽波长范围内测量声图轨迹。超声波测量中的时间和波长范围可以单独通过电子控制来改变。我们展示了超短脉冲在光纤中的传播，如具有复杂时间和光谱分布的拉曼孤子脉冲和超连续脉冲的超声图测量和脉冲重建分析。
We have developed a novel sonogram measurement system with an acousto-optic tunable filter and a nonmechanical cross correlator that uses an electronically controlled, wavelength-tunable, femtosecond soliton pulse. The sonogram trace can be measured in the wide-wavelength region of 1.1–2.1 μm without optical alignment. Temporal and wavelength range in the sonogram measurement may be changed by electronic control alone. We have demonstrated the sonogram measurement and pulse reconstruction for the analysis of ultrashort pulse propagation in optical fibers, such as a Raman soliton pulse and a supercontinuum pulse that have complex temporal and spectral distributions.
