基于InP晶体的双光子吸收特性，提出了一种基于频率分辨光门控的飞秒脉冲表征技术。该技术为脉冲能量低至3.8 pJ的飞秒脉冲在时间谱域的脉冲频率啁啾提供了直接的视觉监测。利用该技术首次对10ghz光纤孤子的脉冲啁啾和基座翼进行了实验表征。
A femtosecond pulse characterization technique is developed using frequency-resolved optical gating based on the two-photon absorption in an InP crystal.The technique provides direct visual monitoring of pulse frequency chirping in the time-spectral domain for femtosecond pulses with a pulse energy as low as 3.8 pJ.Pulse chirping and pedestal wings of 10-GHz optical fiber solitons are characterized experimentally for the first time by this technique.
