A decade ago, flowing gas CO 2 lasers dominated the market for materials processing applications, such as cutting, welding and marking of metals and organics. However, over the past few years, new laser technologies have emerged that give the materials processor more options in choosing a laser source. Specifically these developments include the introduction of higher power sealed CO 2 lasers, the advent of fiber lasers, and improvements in the brightness of direct diode laser systems. The result is that choosing the right laser for a specific application is now a more complex task than in the past. This article reviews the technology and capabilities of all these laser types and provides guidance on identifying the optimal source for a specific need.
