Abstract

The paper describes performance of a novel Nd:YAG laser marker equipped with a liquid crystal device(LCD) mask instead of the conventional metal stencil. The laser marker is characterized by its capability of changing mask patterns, such as alphanumeric characters, freely using a microprocessor terminal within a short period.
