Interesting or not? :)

I managed to remove the crystal from a red laser diode (spare one from sled) and the damn little bastard could be powered directly with batteries connected to very thin leads. It emits red light, could not hold it cause it has absolutely ZERO heatsink, so it is just blinking. the crystal is so small (almost invisible hahahah).... a diode standart pin is thick and massive compared to it.

Is that interesting for you guys, or you have seen it all :p

I made one crappy video with my webcam cause I didn't have anything with better quality at the moment, but still a proof.

Do you want some HQ pictures and Video?

It's not DPSS, and it's not really a crystal either. I think you'd call it a die.

Cool though :)

i have never seen a dpss so small, or come out of a sled. it just looks like an odd red. i am pretty sure cyp is right. it is not a crystal. it is just a regualr optic.

what do you mean by regular optic? The weird colour is because of the camera, I managed to capture ifrared light? I think it is DPSS

I am uploading to youtube the new clip with better pictures and video quality and snapshot of the IR light

From a diode, it's just the diode "die". It's not DPSS, just normal red ;)

If it was IR, it wouldn't be nearly as bright as it is.

well it could be ir. but that doesn't make it dpss... cameras pick up ir... take your tv remote control and point it at your phones camera. you will see what i mean.

by regular optic i mean a regular lens. not a set of doped crystals.

Only CCD cameras pick up IR, and even then, it picks it up as white, not red. I am 100% sure that it is a normal red diode diode, considering the sled and the diode.

this thing is from the red diode from BDR S06J Sled.

didn't you see the picture at the end of the second clip, isn't that ir light, with the other one I can't pick it up. It is the same as from a remote. I had a camera once with IR light for night pictures it is not necessary to be white, could be little greenish, could be little purple... on the LCD you don't see exactly what the CCD or whatever chip it is see :D

Sorry if I am wrong though :)

and how a regular lens produces mixture of infrered and red spectre? There was nothing else in the diode but this thing connected with golden wires to the external connectors - some heatsink and a small filter in the front.
