Strange very small laser diode

I was dismantling some old broken dvd burners for laptops, yesterday, and in one of them, i found a very strange LD .....



Instead a common 3,6mm SmOC, there was a very small closed can red diode ..... it's 3mm dia (not 3,6) at the collar, the can is 1,8mm dia, the total lenght is 4,5mm, the can aperture is 0,7 / 0,8mm approximatively, and the window that close the can is glued outside the can, not inside.

Wondering from where the hell it can came, i never seen one of them, before ..... if i find a way for fit it in something that can act as heatsink, i want to test if it's still working ..... anyway, it was in a 8X DVD burner, so i guess it's nothing special, about the power ..... i just hope they don't start to use 3mm diodes, otherwise it can be a real problem, mounting them in any hobby host :p

if you want a host why not ask jayrob to make you a copper one for it?
OR try an axiz module with heat paste/glue.
It would be hard to find a standard for something like that

If you just want to test if it still works, why not drill a M3 hole into a heatsink or other piece of metal and fire it up? No way to focus it like that, but you can tell if its still working and have some heatsinking during the test.

Yes, that was, basically, my idea, just can't do it here in the shop .....

And about making an adapter, i think it don't worth the effort ..... as i've said, also if it work, how much it can be powerful, coming from an 8X ..... 50 mW or few more ? :D
