To realize a compact and high repetition-rate ultrashort light pulse source a trial assembly was made by combining gain-switched semiconductor laser, fiber amplifier and dispersion-shifted optical fiber. The shortest pulse width of 185fs is reported. Most recently though unpublished a pulse width less than 100fs is recorded, The world shortest value. To potimize the operation condition of the semiconductor laser, a chracterization procedure to evaluate dynamic chirp parameters is developed. The method is based on the experimental data of spectrally resolved streak camera image and a self-consistent fitting algorithm using the short time Fourier transform (STFT) procedures. The extracted parameters successfully predict the optimum soliton compression conditions. The pulse source is applied to an electro-opticsampling apparatus for high speed electrical measurements.

为了实现结构紧凑、重复频率高的超短光脉冲光源，将增益开关半导体激光器、光纤放大器和色散位移光纤相结合，制作了一种实验组件。报道了最短的脉冲宽度为185fs。最近，虽然没有公布，但记录到的脉冲宽度小于100fs，是世界上最短的值。为了优化半导体激光器的工作条件，提出了一种动态啁啾参数的计算方法。该方法基于光谱分辨条纹相机图像的实验数据和基于短时傅里叶变换(STFT)的自洽拟合算法。提取的参数成功地预测了孤子的最佳压缩条件。该脉冲源应用于高速电测的电光采样仪。
