Hi,
I was browsing through the interwebs and I got sucked in to the whole "shiny lasers" thing.
I scoured this forum, a fantastic knowledge base btw, looking up tutorials/hints and tricks etc etc.
I'm looking at building a semi powerful ≈200mW red laser. I have a fair bit of knowledge about lasers and I have been
soldering and making circuits for years. I own a small 5mW green laser and I'm *ahem* Interested in more power.
I have access to a nice (small) lathe and I would love to machine the host/heatsink myself; probably out of aluminum (If I can get it).
Looking through this forum I can tell that safety is Strongly emphasized so I want to assure you that
I'm not some kind of deranged 12 year old boy ; I am definitely getting laser goggles.
Anyways, back on topic. I was just wondering if (any) of these diodes were suitable...
1) Mitsubishi 660nm 200mW
2) 250mW-650nm-Red-laser-diode
I'm planning on using This housing and basically machining my host so that it is an interference fit.
I would probably use a standard lead/acid 12V battery to power the driver/diode at first.
After I make it work, I'll probably invest in some Li-ion batteries or similar. Would a LM317 act as a good driver?
I don't wanna kill my diodes...
To get variable 1.25V - 2.8V.
Any tips, tricks, codes?
:thanks: a bunch.
Regards,
Mike
