Abstract

A steady thermal model of photonic-bandgap fiber laser (PBFL) is presented. Temperature distribution in PBFL is analyzed by heat transfer equations and numerical finite-element method (FEM) separately. Thermal stress distribution caused by the temperature difference between the inner and outer claddings is calculated. The results show that the thermal stresses in this fiber structure are low less than the critical tensile stress in fused silica.

Abstract

The temperature distribution and the thermal stress distribution of Bragg fiber laser are analyzed by solving thermal transfer equations. The changes of refractive index derived from the temperature and the thermal stress are discussed separately. Results indicate that the change of index refraction caused by temperature is larger than by thermal stress.
