我们首次将相干光子播种技术应用于主动锁模激光二极管，并成功实现了单纵模激光二极管工作，侧模抑制比为-20 dB。我们还提出了一种由光栅和平面镜组成的新型脉冲压缩器，它能产生正的群速度色散。获得了11 ps的脉冲，谱宽为0.32nm。这给出了0.63的时间带宽积，这大约是sech 2脉冲的变换极限值的两倍。
We have applied a coherent photon seeding technique to actively mode locked laser diodes for the first time and successfully achieved a single longitudinal laser diode mode operation with a side mode suppression ratio of −20 dB. We have also proposed a new kind of pulse compressor consisting of a grating and a plane mirror, which gives positive group velocity dispersion. We obtained 11 ps pulses with spectral width of 0.32 nm. This gives us a time bandwidth product of 0.63, which is approximately twice the transform limited value for a sech2 pulse.
