How do I measure laser power correctly?
Only trust meaningful data
Every new laser when put into use offers a considerable power surplus, especially in the first few months. Some laser suppliers exploit just such power data (maximum laser power) in the hope of gaining a competitive edge. In our opinion, this data is neither meaningful nor reliable.
What you should know so you can make a comparison
Laser power for material processing lasers is normally given in W [Watt = energy per time unit] However, indication of the effective power is not standardised and so often cannot be compared directly in offers from different system manufactures.
So be very careful when selecting the right laser source!
