take a 445 diode, power it up so it just barely glows and run it through some diffraction grating.
what do you see?

suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.

Mind posting a picture? I don't have a 445nm diode on hand ATM.
I know they emit a teeny bit of green at low power below the blue bar.

A hole in my diffraction grating !
May I must reduce output ^^

lots of little beams?
do you see the beams from the different emitters?

no, you see violet, blue, and green.

Hey, hes right!.
i just did it, and theres a violet line and a green line. but they go away above threshold.
Will there be three phase!!!!

Spontaneous emission? Or lasing?

I do not know to much about lasers but I have also noticed some green around the edges when using one of these 455 diodes in one of my cheap Chinese projectors that Itook apart and installed one into. What causes it?

Pretty cool.

Wiki:The first visible wavelength laser diode was demonstrated by Nick Holonyak, Jr. in 1962.

How about throwing it through a reflect blue, pass green dichro and see what's at the other end?
Spontaneous emission would probably not collimate well enough to hit the other end of the dichro in a tight enough beam.
