After a long day of undergrad lab (Compton effect experiment where each reading takes half an hour!) I decided to take a break and start designing the safety sign for the popomatics (balloon-popping laser) I am building. I wanted to not defer too much from the original sign but add a modern twist to it.
The safety sign must include:
• Wavelength of the laser (532 nm - green laser)
• Type of laser (in this case CW which means Continuous Wave - basically, it has a continuous output and is not pulsed)
• Power of the laser (100 mW)
• Class of the laser (here, it is Class 3B which means you cannot look at the beam directly as it is hazardous to the eye but if you look at diffuse reflections for instance reflections from matte surfaces, preferably dark matte surfaces are not harmful - hence the need for the 'safety screens' I mentioned in the previous post here).
And also some safety statements about the permitted users and informing the user to not stare directly at the beam.
Here is the previous sign:

And here is the new one!
