A TEA CO2 laser has sufficient energy to produce marks by forming a reduced image of a stencil-type mask on a product or component virtually instantaneously (10-6 sec.). This simplifies beam and component handling compared to dot matrix or engraving-type markers. The characteristics of the TEA CO2 laser are appropriate tor this technique given its proven efficiency reliability. Examples of application in the electronic packaging, bottling, consumer packaging and other industries are given. Also discussed is a new laser emitting in the ultraviolet spectral region that has poss1bilities in metal and semiconductor marking areas.
