Abstract

Cladding light strippers are essential components in high-power fiber lasers used for removal of unwanted cladding light that can distort the beam quality or even damage the whole fiber laser system. In this study, an Atomic Layer Deposition system was used for the first time to prepare the cladding light stripper devices using a 40 nm thick zirconia layer grown on optical fiber. The thickness of the zirconia coating was confirmed using the Scanning Electron Microscopy (SEM) and the Ellipsometry techniques. The elemental analysis was also performed using the wavelength dispersive X-ray spectroscopy technique. The Raman spectroscopy and XRD data confirm the structure of the atomic layer deposition-grown zirconia thin films to be predominantly amorphous. The cladding light stripper devices formed using the zirconia thin films with the lengths of 8.5 and 15.5 cm were able to strip approximately 30% (~1.5 dB) and 40% (~2.3 dB) of the unwanted cladding light.

原子层沉积氧化锆薄膜在光纤上的应用
包层光剥离器是高功率光纤激光器中的重要部件,用于去除可能扭曲光束质量甚至损坏整个光纤激光系统的不需要的包层光。在本研究中,首次使用原子层沉积系统,使用在光纤上生长的40nm厚的氧化锆层来制备包层光剥离器器件。使用扫描电子显微镜(SEM)和椭圆仪技术确认氧化锆涂层的厚度。还使用波长色散X射线光谱技术进行元素分析。拉曼光谱和XRD数据证实了原子层沉积生长的氧化锆薄膜的结构主要是非晶的。使用长度为8.5和15.5厘米的氧化锆薄膜形成的包层光剥离器装置能够剥离大约30%(~1.5分贝)和40%(~2.3分贝)的不需要的包层光线。
