Default Re: How does a laser blind you?

Exactly Diachi. Yes, IR or even UV. IR doesn't fluoresce much and can be totally invisible to the naked eye. Whereas UV can cause fluorescence allowing its dot to become visible. The danger of high powered UV though is any UV glare can be potentially hazardous to unprotected eyes resulting in cataracts in severe cases.

And as for the photonic energy. Yes, the power is the same. Photonic energy only becomes important when we are talking about ionisation or phenomenon such as the photoelectric effect.

I forgot about the photoelectric effect. I remember we experimented with that way back in High School when we were doing our section on light/lasers.

Another one: Matters for things like fluorescence too.

Default Re: How does a laser blind you?

Yep. My school never allowed experimentation with lasers. Maybe that's a reason why I'm so adamant now.
In order to test thing like ray diagrams, we have to use a ray box, not lasers.

BTW I have seen a video even using green laser to power red LED. Interesting...

Edit: Well it seems it was not the video but this pic:
