Hello there, I enjoy creating lighting projects to illuminate my house that are enjoyable and are pleasing to the eye. I've been interested in using lasers for awhile, but am concerned about the possible damage to the vision of myself and my house guests.
I have stumbled across a guide based on creating a laser light show through the use of a laser, mirror glued to a headphone speaker, and a diffraction grating plate. I do not desire an incredibly powerful light show, instead the same process with a much weaker laser that can be left on 24/7 (and not overheat) to light up the ceiling in my living room.
Safety
With a 5mW laser (the legal intensity allowed by the U.S. FDA to be owned without a reason) and the laser passing through a diffraction grating, will a guest who looks into one of these diffraction beams (either accidentally or on purpose) damage their vision? As this is intended to be left on 24/7 or mainly at night, it needs to be safe to have in the living room. Are there any precautions I should look into for constructing this project? (I am assuming that construction with the single beam will be dangerous, yet diffracted beams will be much weaker)
Quality
This is not supposed to be a distraction in the house, but whenever someone walks into the room at night will see the ceiling illuminated with glowing laser patterns. Is a 5mW laser bright enough to be visible on the ceiling after having passed through a diffraction grating? From reading peoples comments about lasers, many people desire lasers that pop balloons or cut tape (high powered - 50mW+). Can I have a successful show with a laser weaker than 5mW (lower power would be preferable)?
Heat Dissipation
From what I have been reading, leaving a laser turned on for continued period can burn out or damage the laser. What kind of lasers can I purchase that can be left on indefinitely?
Any information would be greatly appreciated, and I am very interested to begin to use lasers for projects.
