| 摘 要： | 采用纳秒激光器作为泵浦源,在光子晶体光纤中实现宽带超连续谱输出,并研究泵浦脉冲重复频率对超连续谱产生的影响.在重复频率150 kHz、峰值功率256 W时,利用25 m长光子晶体光纤实现输出功率为0.76 W、光谱范围超过1 200 nm的超连续谱输出.利用该激光器的重复频率可调性,选取重复频率50 kHz和100 kHz的泵浦脉冲,对平均功率相同、重复频率不同的3组泵浦条件所形成超连续谱进行对比,发现在平均功率相同时,重复频率越低的泵浦脉冲获得的超连续谱宽度越宽. |

| Abstract: | The wideband supercontinuum was achieved in a photonic crystal fiber by a nanosecond pulsed laser.The influence of repetition rates of pump laser on the supercontnuum generation was studied.A 25-m-long photonic crystal fiber was pumped at the average peak power of 256 W and at the repetition rate of 150 kHz.It put out supercontinuum with 0.76 W power and the spectral range of over 1 200 nm.According to the tunability of the repetition rate of this laser,the output supercontinua pumped at the same pump avera... |
