Apparatus and method for calibrating a laser deposition system

摘要

A method of calibrating a high energy beam with a material source, the method comprising the steps of:-
using the high energy beam to provide an aperture, depositing material from the material source towards the aperture for a selected length of time and collecting the material which passes through the aperture, and adjusting the position and / or alignment of the material source relative to the high energy beam dependant on a comparison of the amount of material collected with a predetermined value.
