Fundamental Study in Microjoining of Fused Silica Utilizing Laser Radiation

Abstract

A laser micro joining process for the radial geometry of a fused silica fiber connector is developed. The special characteristics of fused silica are described and their importance for the process is evaluated. The heat flow in the glass is simulated mathematically and the results of welding experiments are discussed. The peculiarities of the radial geometry of the joint enforces a process, using the fiber as filler material to fill a gap in the seam.
