Abstract

The effects of spatial beam profile on weld dimension and weld quality is really important for laser spot weld. The following paper discusses the characteristic of beam waist for high power ND:YAG laser. It was found that, beam spatial profile changes considerably along the beam waist. Also changes of focal plane with the beam power is characterized.
