WHY LASER WATTAGE MATTERS

We’ve talked a lot about laser wavelength so far, but another key determinant of how fast a machine can mark is power output.

While laser wavelength is a measurement of light energy, watts (W) is the unit of measurement for laser power output. For example, a typical industrial fiber laser marking machine will run anywhere from 10W to 100W of output power. They deliver high speeds and deep, permanent marks.

Most green marking lasers on the market today only deliver about 4W to 6W of power output. In general, that translates to relatively slower speeds and shallower marks.

How can you get the speed and quality you need? Don’t give up on green lasers just yet because, as they say, necessity is the mother of invention.
