成功地研制了一台波长和频率可调的主动锁模光纤环形激光器。波长可调范围为1534～1565 nm,频率范围为2.4～2.6 GHz, 产生的光脉冲时间带宽积接近于变换极限。经过改变调制器的直流偏压得到了重复频率为5 GHz的光脉冲。对实验中的有关原理进行了分析。

A continuously tunable ring laser of repetition operation is successfully made. The range of the tunable wavelength is 1535~1565 nm. The range of the repetition rates is 2.4~2.6 GHz. The time bandwidth product is close to the transform limit. Optical pulses with a repetition rate of 5 GHz are obtained by changing the direct current bias voltage, and the relative experimental principle is analyzed.
