Description

Small-scale CO2 laser energy delivering medium capable of performing stable, flexible and high-strength is crucial in extreme CO2 laser processing environments, especially for minimally invasive surgery operating in environment with high-humidity, twisty and narrow channel. In this paper, we proposed flexible and robust multimaterial infrared fibers made of selenium-based chalcogenide glasses and thermoplastics polymer with low optical loss of 7.18 dB/m at 10.6 μm. The fibers were fabricated by a hybrid process combining double-crucible method and fiber thermal drawing method. Customized composites of commercial polyphenylene sulfone resins and polyvinylidene fluoride were used as the jackets, thereby the fibers exhibited hydrophobicity, thermostability, high tensile strength up to 10 MPa and low bending stiffness as low as 8.48×10-7 N·m2. Moreover, it was demonstrated that the fiber can be used to deliver CO2 laser energy for fabric cutting and biological tissue ablation, making them attractive for CO2 laser material processing, especially in minimally invasive laser surgery.
