Laser Power Requirements

Laser Power Requirements For 30 micron thick sheets
Material Spot size (mm) Laser power (W)
Polymer 1 10
Polymer 0.3 1
Polymer 0.1 0.1
Al 1 1000
Al 0.3 100
Al 0.1 10


If the material is plastic wrap or aluminum foil thickness, the power required is about three times as much. So basically being able to focus the beam not only can give you smaller channels, but it also reduces the required laser power.
