Medical Device Link . Laser Micromachining of Medical Devices
Excimer, CO2, and solid-state (primarily Nd:YAG and Nd:YLF) lasers represent the three most common types of lasers used in industrial micromachining applications. Each has its own unique characteristics, and together they provide very complementary capabilities (see Table I). (Tables and figures
