I can't seem to find a clear answer to this anywhere. Presumably they glow brighter the brighter the light source is. The best I can find are some sensitivity graphs like Thorlabs has where they show the normalized emission band. But this isn't relative to the incident light right?

I think this is a pretty important question because if I have a > 500 mW laser, I would like to know what percentage of that is now diffusely glowing and bypassing my safety goggles. Maybe I'm being an idiot. If anybody can clear this up for me, thank you.

And I know it's probably not as simple as just a plain percentage. I'd bet it changes with intensity
