What is this and what does it do? Found it in one of those class 3b lasers

Also had this in it

Looks like some kind of optical component
what does the label say?
must have a name or an alphanumeric label of some kind on it?
google it and tell us what you find

Looks like a laser diode.

>> No.1518279

that is the laser with a heat sink attached.

For one it is an electrical component
Two it doesnt do anything since you ruined it

Other than the laser diode itself. It can have a small cheap driver circuit that provides a constant flow of current rather than voltage. This is almost all laser pointer designs.
More expensive lasers have a photodiode inside the packaging of the laser and is used to detect the light output by a dedicated laser diode driver which keeps the laser very constant in it's output intensity at varied temperatures.

I honestly can't see shit in your photos.
