In this study, we demonstrate the generation of soliton mode-locked pulses from an erbium-doped fiber laser (EDFL) cavity configured with 8-Hydroxyquinolino cadmium chloride hydrate (8-HQCdCl₂H₂O) based saturable absorber (SA). The thin-film of 8-HQCdCl₂H₂O was prepared by embedding the 8-HQCdCl2H2O into polyvinyl alcohol (PVA). The soliton mode-locked of EDFL was obtained from laser cavities lengths of 33 m, 53 m, and 103 m. These EDFL cavities of 33m, 53 m and 103 m show repetition rate (pulse width) of 5.6 MHz (950 fs), 3.6 MHz(1.02 ps), and 1.9 MHz (1.53 ps), respectively, at maximum input power of 167 mW. The presence of Kelly sidebands in optical spectrum was obvious with of EDFL cavity 33 m. This indicates that the pulse operation was shifted from stretched pulse to soliton regime with the reduction of cavity length. The soliton mode-locked laser operated at 1563 nm with the shortest pulse width of 950 fs and thus it could be applied in optical communications.

在这项研究中，我们演示了由掺8-光纤激光器（EDFL）腔产生的孤子锁模脉冲，EDFL腔配置有基于8羟基喹啉基氯化镉水合物（8-HQCdCl ₂ H ₂ O）的饱和吸收器（SA）。8-HQCdCl ₂ H ₂的薄膜通过将8-HQCdCl2H2O嵌入聚乙烯醇（PVA）中来制备O。EDFL的孤子锁模是从33 m，53 m和103 m的激光腔长度获得的。在最大输入功率为167 mW时，这些33m，53 m和103 m的EDFL腔分别具有5.6 MHz（950 fs），3.6 MHz（1.02 ps）和1.9 MHz（1.53 ps）的重复频率（脉冲宽度）。 。EDFL腔为33 m时，光谱中明显存在Kelly边带。这表明随着腔长度的减小，脉冲操作从拉伸脉冲转变为孤子态。孤子锁模激光器在1563 nm处工作，最短脉冲宽度为950 fs，因此可用于光通信。
