Abstract This work reports mechanically exfoliated indium tin oxide (ITO) as saturable absorber (SA) for Q-switched operation in fiber lasers. The ITO is mechanically exfoliated from 99.99% pure In2O3/SnO2. As ITO has a broad operational wavelength from visible to infrared, indium tin oxide saturable absorber (ITO-SA) is incorporated into ytterbium-doped fiber laser (YDFL) and erbium-doped fiber laser (EDFL) cavity for Q-switched operation. The Q-switched spectrum was observed to be centered at 1038.25 nm for ytterbium-doped fiber and 1557.8 nm for erbium doped fiber. The ITO-SA has a linear absorption of 2.25 dB and 2.5 dB at 1 μ m and 1. 5 μ m respectively. A narrow pulse width was observed in the EDFL operating at 0.95 μ s. For the first time, ITO-SA is incorporated to YDFL cavity.

机械剥离氧化铟锡作为 Q 开关掺镱和掺铒光纤激光器的可饱和吸收体

摘要 这项工作报告了机械剥离的氧化铟锡 (ITO) 作为可饱和吸收体 (SA)，用于光纤激光器中的 Q 开关操作。ITO 从 99.99% 的纯 In2O3/SnO2 机械剥离。由于 ITO 具有从可见光到红外的广泛工作波长，因此将氧化铟锡可饱和吸收剂 (ITO-SA) 并入掺镱光纤激光器 (YDFL) 和掺铒光纤激光器 (EDFL) 腔中以进行调Q操作。观察到掺镱光纤的 Q 开关光谱集中在 1038.25 nm 和掺铒光纤的 1557.8 nm。ITO-SA 在 1 μ m 和 1. 5 μ m 处的线性吸收分别为 2.25 dB 和 2.5 dB。在 0.95 μ s 的 EDFL 中观察到窄脉冲宽度。首次将 ITO-SA 并入 YDFL 腔体。
