研究目的
To predict the laser fiber refractive index more accurately by applying a stress-induced index change model to the measured preform index profile data.
研究成果
The stress-induced index change model improves the prediction of fiber refractive index from preform measurements, enabling better process feedback and higher fiber yields. The model provides a physical basis for understanding index changes, unlike statistical models which are limited by existing measurement data.
研究不足
The model's accuracy is limited by the availability of material parameter values at high temperatures and the assumption of linear additivity for some material combinations.
