Abstract:
1. A method of calibrating an ablation system that generates an ablation beam, the method comprising: ablating an article with the ablation beam generated by the ablation system so as to form a test location having an ablation depth, wherein the article comprises a test article material; separating light from a light source into a first beam and a second beam; transmitting the first beam through a first thickness of test article material at the test location while transmitting the second beam through a second thickness of test article material at a reference location, the reference location disposed outside of the test location and the first thickness different from the second thickness; determining an ablation beam characteristic based on a phase relationship of the transmitted first beam and the transmitted second beam; and calibrating the ablation system based on the determined ablation beam characteristic.
