Good deal on a 1000mW+ DPSS Argon diode?

I found a 1000mW+ DPSS Argon diode on the internet and I'm wondering if anything under $100 is a good deal? I believe it's the diode that is in the more expensive 445nm lasers and not a cheapie like the Casio diode?

Not sure though, I'm a noob, but I'm planning on spending about $250 on a good 445 laser!

Another question, what's the best housing to use? I've read the brand Rayfoss a lot. Any pointers? I'd be happy with links to the best tutorials. I'm still searching around. As you can see by join date and post count, I'm a newbie. Someone take me under their wing and teach me the secrets! :bowdown:
 





Could you please post a link?

Because this sounds really weird : argon lasers use gas, yet you are also talking about DPSS (IR diode pumped crystals) and diode. This is IMO a 488nm DPSS laser, but at 1W??? Not sure about this...
 
They try to pull in other buyers with "DPSS" and "argon" even though it is neither.
 
488nm is either direct double with a single crystal and a VCSEL diode or is OPSL. The Casio diode isn't a 'cheapie' it's a 1W Nichia 445nm diode created using the InGan substrate. A 445nm laser is a 445nm laser.

Edit: Cyparagon kinda covered it, sellers will add commonly used terms to their listings to get more results in searches.
 
DPSS Argon diode? Sounds like the seller has no idea what hes selling. DPSS means
that the laser used a semiconductor pump diode and light converting crystals to
acheive a desired wavelength. Argon is a type of gas laser that uses gas as the laseing
medium and doesn't use crystals.

EDIT: Looks like im a little slow on the draw

This is just a regular Casio projector diode, nothing special there. You can get them cheaper in the GB section.

Sorry, I meant cheap in relation to a blue laser normally costing thousands at wattages <20mw, even.

I suppose instead of even worrying about getting ripped off on Ebay the question to ask you all is, where do you get your diodes, and can you help me get something together or someone even build me something around $200? I'll go $250, but I'm hesitant. I can even settle for a green if I have to. I just want the most power for my buck. I've had an aspiration to start a wifi business here in West Virginia and having a nice powerful laser to align dishes and access points over 2 miles+ would be GREAT. Blue probably isn't the wisest thing to use anyway. I'd say green would be smarter or will a >1w do the job? I like the blue color and prefer it over green. I'm also red-green color blind, that's another reason why, but it's not a really big deal.
 
Get yourself a 18650 (did I get the number right?) kit from Jayrob with full copper heatsink and "hot option" (if you never built a laser before) and take a look in the Group Buy section of the forum for good deals on these diodes.

Searching the forum now! Thanks. If anybody wants to make a buck building one, I'm still open to that option. lol I'm not very good with the whole soldering thing (if it's even needed with a kit?!?! I'm sure it is since the diode has to be attached somehow.) :confused:

I'm not going to get a dot out of a 445, am I? It's going to be a line, isn't it?

At 2 miles it certainly will be since a mulit-mode diode. For your uses, aligning dishes and whatnot, I would recommend green DPSS
 
For aligning dishes at 2 miles... heh. good luck... at 2 miles, a initial 2mm beam with 1 mrad divergence will be 10.5 FEET in diameter. And these 445 diodes have a LOT higher divergence than that.

For what you want to do, all you need is a compass, an inclinometer, decent topographical maps of the area, and a little bit of math... Been there, done that. While dishes are highly directional, but aren't exactly pinpoint devices. You won't notice any difference in signal strength if the dish is a couple degrees off.. though if you have a good compass, it's not hard to get it dead on.

Also, if it's a populate area, your going to have troubles with intereference.. everybody and their grandmother has AP's in their houses, and there's really only three frequencies that actually have no overlap.. 1, 6 and 11.(at least on 2.4ghz) And 2 miles over residential, your bough to have a few AP's on all those channels in your signal path.

Rain fade is also an issue.. 2.4ghz is what water absorbs.
