Power – The Praxair Laser Inspection looks at the power 1.600
delivered to the work piece and compares it to the power 1.400
developed in the resonator. If your output coupler, mirrors 1.200
and focusing lens are performing normally, the wattage 1.000
developed in the resonator should be wattage delivered 0.800
to the work piece.
0.600
Shape: Beam shape is defined in a three dimensional, 0.400
computer-generated graphic, and displays the beam 0.200
ellipticity, height, average diameter and intensity. A 0.000
compromised shape will cause the laser cutting speed 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9
to diminish, while increasing dross on your parts, labor, Time
power and gas expenses.

Praxair will provide you with an analysis of your beam profile
during testing and a written report following the review. This
will assist your laser service provider in determining where
corrections and adjustments need to be made. In turn, this
may allow you to save money on repairs and may lead to
higher productivity.

Get the most work out of your laser beam between planned
maintenance cycles. Call your Praxair representative for
