Safety
- MTU's Laser Safety Guide
- MTU Physics Dept's Laser Safety Guide
- You need to _____ before you can use this system.
Laser Power Requirements
| 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.
