Abstract

Abstract

A optical system,used as an optical Pen in a large size marker,is employed to fucus the Nd:YAG laser beam transmitted with the optical fiber.The focused beam diameter can be less than 0.2mm or 0.1mm and can be controlled by hand.The optical Pen may mark the workpiece or weldingelectronic elements.
- aser mark,
- Nd: YAG laser,
- focus,
- multimede fiber
