摘要
基于非线性放大环形镜,设计了一种全正色散掺镱光纤锁模激光器。在抽运功率为80 mW的情况下,该掺镱光纤锁模激光器可以实现平均功率为7.8 mW的稳定输出。输出激光脉冲的重复频率为9.9 MHz,中心波长为1064 nm,脉冲宽度约为18 ps,相应的光谱宽度为0.18 nm。该激光器具有结构简单、自启动、稳定性高的优点。
Abstract
This study presents the design of a normal-dispersion polarization-maintaining Yb-doped fiber laser based on nonlinear amplification loop mirror. Stable output of a picosecond pulse train with an average power of 7.8 mW is realized from the Yb-doped mode-locked laser at a pump power of 80 mW. The output pulse train has a repetition rate of 9.9 MHz, a central wavelength of 1064 nm, a pulse duration of ~18 ps, and the corresponding spectral width of 0.18 nm. The designed laser has the advantages of a simple structure, self-starting operation, and high stability.
