GGW-H20L blueprint/parts ID

Hey, all! I have a GGW-H20L sled that I used the 405nm out of. My question is, which one of the two left over diodes is the red? I've been searching and can only find info pointing out which diode the 405 is. I looked high and low for a diagram, to no avail. From what I've read, the red's sound decent, but I'm just a noob that doesn't know any better Thanks for any input.

if you are facing the optics side with the diodes pins facing up the red should be the one to the left.

double check me by searching "lcc extraction" or similar wording with ggw.

Easy way to tell is the red diode has a can twice as long as normal

Here ya go

Perfect! Thanks, guys Now, the last question. Is the last diode worth using for a green build? Green is the only one I haven't read a whole about.

Are you trying to fix a broken green laser pointer you have or make one from scratch? If you trying to make one from scratch you might want to read this first:

I was just curious if it was worth saving for a future endeavor, or if I should just use it to practice soldering on, then toss it. Thanks!

Practice and toss. You can get much better IR diodes for little cost.

Peace,

The IR in that sled is 780nm, not quite the wavelength that would be useful in a 532nm setup. In fact it wont produce any 532nm.

Its a good diode for night-vision illumination etc and should give you approximately 200mW of near IR.

For 532nm you want to pump with an 808nm diode which are fairly cheap now. Just be sure not to purchase an off spec 808nm it wont yield the desired results. Good 808's can be found for a reasonable price on ebay by the seller snoctony.

Great post Blue, I'll just add some info on 780 nm,

Unlike most common IR, this is case NEGATIVE , just like RED diode (not case+ like other 808nm and higher ),
It will survive up to 250mA of current with good like and it will produce little amounts of heat due to the fact it's very efficient (well, for a laser diode),

It's a great diode to practise some skills on - and even rewarding if you succeed in powering it, which is not the case in , for example, PHR red/IR combo - 30mW of power out of it max

Have phun!

Dont forget they are single mode and for an NIR will give a nicely shaped dot at the end of the beam. Most NIR namely 808's give a line or rectangle at best even at low powers. Its pretty rare to find even a 150mW 808 that does not require FAC. 780's are perfect for scopes etc.

Heh, for some reason I had the red and the IR locations switched in my mind. I was under the impression that I had LED'd the red diode from my sled a few weeks ago (that also explains the holes in my vision j/k). I guess i need to grab the other diode out of the sled so i can run the tests i was planning.
