Mode Coupling in Optical Fibres Used for Laser Spot Welding

Abstract

Beam handling via fibres facilitates laser spot welding in the electronics industry. However, it demands some insight into the optical transmission properties. One interesting aspect is the relation between the laser focusing angle and the exit angle of the laser light at the end of the fibre. Whereas in an ideal straight step index fibre this angular distribution would basically be preserved, it is usually broadened due to fibre bends.
