405 and diffraction gratings

I noticed that for some reason when I look at my 405-445 lasers while wearing my diffraction grating glasses there is a full spectrum coming off the dot like it if you were to look at a white light. It only seems to happen when I am looking through them. It does not happen when just the laser is put through. It does this no matter what object I point it at. When it is pointed at a florescent object it causes the corresponding part of the spectrum to light up too. Do 405-445nm lasers cause a small amount of florescence in everything, or is there something else I am missing?

I looked toward (not directly at obviously) a 405 through my D.G., all the dots were violet. I only see the spectum thing looking at white light sources
