Mike klos laser mechanisms converting to millimeters that s 1550 watts mm 2.
The thicker the material to be cut the more crucial a high laser power is in order to achieve a good quality.
Sheet metal cutting requires a power density of 10 6 watts in 2 source.
The two most common types of laser cutting machines are fiber laser and co 2.
A 20w fiber laser will have little trouble marking most metals where as a 20w co2 laser has pretty much zero chance.
If you d like to learn more about ablative laser cutting check out this article on micron scale manufacturing.
Always check the laser s power or at least what materials it can cut.
As a rule of thumb the following applies for acrylic for example.
As a reference a 40 w laser can cut through paper cardboard foam and thin plastic while a 300 w laser can cut through thin steel and.
By far acrylic is the cheapest material to laser cut.

10 watts per millimeter.
We have compiled this guide for the laser system that we sell which gives you a good idea of all kinds of materials that a laser can mark engrave drill and cut from the commercially available options that we provide.
Steel sheet thickness in mm.
Co 2 lasers use an electromagnetically stimulated gas typically a mixture.
Steel and stainless have a relatively high absorption of the wavelength associated with a co2 laser which is why you will see them listed as being able to be cut on a lower wattage gas assisted co2.
As aluminum contains high thermal conductivity and is reflective a higher concentration of laser power is needed to initiate cuts compared to steel s less.
