Lasers Types And Laser Power
Lasers work in different ways that are usually attributed to the type of laser that is being used. A combustible material such as wood must not, for example, be cut with oxygen, as the work-piece would catch fire. Depending on which laser is used, its power must also be adjusted accordingly to match the type and thickness of the material that is being worked on.
More power doesn’t necessarily mean better results. A reduction in the laser power may be necessary to achieve high accuracy on complex shaped work-pieces or very small parts. In contrast a laser power of at least 1000 W is needed for cutting carbon steel thicker than 5/16”.
As with the laser power, the pulse frequency can be matched to the relevant machining task. For example, it is recommended small contours are cut with reduced pulse frequency. The pulse frequency is also reduced when piercing in the ramp mode.
