Infared lasers build question's

[laserwanabe]

I wanted to build a IR laser that can fit into an aixis module. Anywhere from 500mw-1W, I would like it to be run off of a 9v if possible. I looked on eBay, but they were like TO-5 and I don't really get that...

So basically an 500mw IR (doesn't have to be 808, what ever is cheap and burns good) that can fit into an aixis module and can be run off ~9v.

Links and guides, help ect. appreciated.

There is plenty of information floating around here.
There is a thread it the Tutorials forum, in this forum, and I forget where else.

For 500-1000mW you would probably be best with 808nm. It's cheap and not completely invisible so it should be easier to work with.
At that power, it may be difficult to find a 5.6mm diode. Also, an aixiz module would not be ideal for heatsinking. Powering a diode rated for a watt would require at least an amp.
C-mount is your best bet, but you may be able to find a 9mm diode.
Search for E-bay seller Snoctony.

Here is a list of all kinds of laser diode package types:

well I want it to be portable so i don't want a giant heat sink. I don't know much about c-mount optics wise, I have seen how they are constructed.

Is there anywhere where I can find a pre-made module that I can just heat sink... or something along those lines. Who sells 1 amp drivers?

You'll need a Meredith module for 9mm diodes to make a small module. It's very difficult to find 5.6mm diodes at powers much above 250mw at IR wavelengths, but 500mW and 1W 9mm diodes are fairly common. Here's a link to a 9mm 1W diode: http://cgi.ebay.com/1000mw-808nm-la...ryZ53141QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

Snoctony also sells many other types of diodes, so it's well worth your time checking the rest of his listings out..

Heatsinking is a must at those powers. An LM317 driver will handle up to 1.5A.

So basically one of those diodes, a Meredith module and a LM317 will build me a complete working laser.

Plus I'm going to have to buy goggles if i get into IR. I may consider just getting a 250mw red so I can see what i'm doing, I wont be pointing it at any reflective surfaces so it might work better.

I want more burning power but a 500mw IR build is over 2X the price of a dilda laser.

Regarding the highlight above: Yes. That would work.

An 808nm IR system has the advantage of being able to pump DPSS lasers. If you have a working 808nm laser, you can use it to experiment with building your own green laser.

Do you think it would be easier to simply buy a dx green pointer and remove the crystals? I have heard some good and some bad results. I may consider that but i think going back to red might be better for what I want.

if you do that, focusing becomes a problem.
