Default Extracting a diode from a circuit board?

So I am fairly confident that there is a diode in this as I can see three pins and a lens on the other side, but the question is how could I get it out? I know I'll get some responses such as try searching, but after reading some topics, I don't necessarily know if those cases apply to this one.

Desolder it. Keep contact time short

As hwang21 suggested unsolder the diode from the board without leaving the iron on the pins for too long...I'd suggest you buy some solder wick to make the process easier!

Would that happen to be a board from the laser printer?

If so, I wouldn't put up too much hope on it, those are near-infra-red diodes, and very weak ones at that.

If you really want to get it out, yeah. Soldering iron, and a desoldering pump and/or solder wick.

Default Re: Extracting a diode from a circuit board?

Thanks for the responses, I'll be taking it out soon. And to Eudaimonium, you would be correct. I'm not so much attempting to make a strong laser out of it as much as I am trying to get experience in this. I knew it was an infrared Class 3B laser diode. I also know as a beginner not to mess with it too much as infrared is just as dangerous if not more dangerous than any other laser. Thanks though.

Well it's not really any more dangerous than other lasers, but it's not as interesting as other lasers.

But for practicing various extraction and solder skills, it'll be great! You let me know if you need any help, just shoot me a PM and I'll do my best to help you out.
