While I fully agree with MosherIV — you should never look at a laser diode to see if it works(1) — that doesn’t look like a laser diode.
It seems to be a normal LED with collimating lens on top of it. The board itself is sold as “power distribution board”, so I expect it is either an indicator or the emitter part of a detector (e.g. of the case being open). Seeing the other side of the board would help.
Also, please consider adding attachments directly to your posts, instead of using 3rd party services.
