Large Core Diameter Laser Energy Transfer Quartz Square Core Optical Fiber

Product Description

Square Core Fiber (SCF)
1. Introduction
Our square core fiber is a kind of large core diameter laser energy transfer fiber with special structure, which is mainly used in the fields of laser high power transmission, homogenization, imaging, spectroscopy and so on. Its structure includes square high purity synthetic quartz core, fluorine doped quartz cladding and coating. The typical NA values of core and cladding are 0.12 and 0.22. Square core fiber can significantly improve the coupling efficiency with semiconductor laser, has excellent spot homogenization effect and shaping function, as well as a strong advantage in the field of laser cleaning and laser beam shaping.
