| 摘 要： | 本文首次报道１．３μｍ单模超短脉冲产生及压缩实验。通过梳状波电脉冲直接调制ＤＣＰＢＨ－ＤＦＢ半导体激光器，获得２２ｐｓ单模光滑脉冲；然后利用Ｇ－Ｔ干涉仪压缩得到近变换极限超短脉冲。脉宽为９．３ｐｓ，峰值功率超过２００ｍＷ，重复频率１ＧＨｚ，时间带宽乘积为０．３９，脉冲压缩比为２．４。最后对实验结果进行了讨论。

| Abstract: | The generation and compression of 1.3 μm single-mode pulses was reported for the first time. The pulses with duration of 22 ps were obtained by modulating a DCPBH-DFB laser diode with comb current pulses, and nearly transform-limited pulses were observed with compression of a G-T interferometer. The pulse-width is 9. 3 ps, the peak power is over 200 mW and the repetition is 1 GHz. The time-bandwidth product is 0.39 and the compression ratio is 2.4. The experimental resultS are discussed in this paper. |
