The importance of focal positions in laser cutting

January 8, 2010 | By Frank J. Arteaga

If the proper laser beam focal position and projection shapes are maintained within the material to be processed, the balance of the requirements necessary to producing a consistent, high-quality laser-cut are kept to a minimum. That's why it's important for laser cutting equipment operators to know the rules of laser beam focusing.

Purging the plenum for better laser cutting

June 23, 2009 | By David J. Connaughton

Typically, compressed air or nitrogen circulates in the plenum to ensure that water, dirt, dust, smoke, haze, and solid particulate matter are absent so that the mirrors in a laser resonator do not become cloudy. In recent years, membrane air dryer systems that provide drying and removal of particulate matter have been developed for flushing the beam path.
