在这个项目中。本文拟从实验和理论两方面对二极管激光器产生的超短光脉冲以及通过光脉冲压缩控制其宽度进行研究。通过这个研究项目，我们成功地获得了以下结果：利用大信号理论对半导体激光器产生超短光脉冲进行了分析研究。结果探讨了激光参数与操作条件的定量依赖关系。提出了直接脉冲压缩方法，并利用G-T干涉仪进行了实验。由此获得的最短脉宽为6.5 ps，压缩比为4.6。本文还对实验结果进行了分析，并对实验结果进行了很好的解释。对多量子阱（MQW）激光二极管产生短脉冲进行了实验研究。结果表明MQW激光二极管具有较好的短脉冲产生特性。

In this project. We intend to pursue both the experimental and theoretical studies of the ultrashort optical pulse generation from diode lasers and their width control by the optical pulse compression. The following results have been successfully obtained through this research project.A. The analytical studies have been done on ultra short optical pulse generation from semiconductor lasers under the large signal theory. The result explores the the quantitative dependence on the laser parameters as well as operating conditions.B. The direct pulse compression was proposed and performed experimentally using the G-T (Gires-Tournois) interferometer. Shortest pulsewidth thus obtained was 6.5 ps with the compression ratio of 4.6. The analysis was also performed and experimental results were well explained.C. Short pulse generation from multiple quantum well (MQW) laser diode was also studied experimentally. The result implies MQW laser diode has superior characteristics for the short pulse generation.
