发明名称 Laser marking method
摘要 <p>The method involves taking a support (12) formed by a metal that is highly absorbent at wavelength for converting a part of light energy absorbed into thermal energy. An article (14) is arranged directly against the support to form sufficient thermal contact between the article and the support to transfer the energy from the support to the article. The article is placed between a laser (10) i.e. neodymium-doped yttrium aluminum garnet laser, and the support. The support is locally illuminated through the article to generate sufficient energy at the support surface.</p>
