Re: Looking for Green or Red 200mW or more laser..
200mw red = $200 (plus shipping)
200mw green (excluding DX, which are of questionable quality) = $600-$800 (plus shipping)
Now for jsut playing around, you shoudl look at dealextreme, you can get a 200mw green laser for, I think $120 USD, however these put out anywhere from 100-220mw of green and usually a noticable ammount of IR. It's a total throw of the dice when ordering the high-end DX lasers (the low-end ones seem to be of good power, though all of them are more fragile than a NOVA or Laserglow
Keep in mind that green lasers are DPSS, which means they use a special crystal alignment to turn IR into green light, this alignment can get missaligned by jolts and jars, so you have to be careful. A red laser, however, is a bare diode and can be downright abused and still work (my reds routinely fall out of my pocket onto a hardwood floor and havn't had any problems)
if you want a green, the three I've heard good thigns about are Atlas, NOVA, and LAserglow. IF you want green power, you really cant beat the Laserglow's Hercules line. though the high-pwoers are up in the 700-2000 USD range...
IF you're going to be carrying it around and whipping it out randomly to play with... er I mean "Scare tirrorists"
then you might better get a red unless you want to settle for less pwoer or a much higher price. TRuth be told if you want raw power, IR is the way to go. I can get a 500mw IR diode for <$50 (soemtimes you can get a 1W (1000mw) for this price) and the other laser components for ~$10 and build a major burner. (I recently saw a full laser (now handheld but oculd be made portable) that was 3W (3000mw!) that sold for <$200 on ebay.) Even prebuilt IR lasers are monsters at low costs, PSeudo on here has a 400mw near-IR laser he sells for <$400 (closer to $300 IIRC) compared to the costs of reds and greens the cost per miliwatt is laughable.
Now contraversially, I will state that I've heard some bad things about WickedLasers's greens (excluding their 5mw core) and about DragonLasers (the former having problems just keeping the beam steady and the latter supsoedlt selling them at higher mws than they really are (i.e. a 75mw sold as a 150mw) This is pure rumor-mill material, though, as I've not bought from DL and my only purchase from WL was a red pulsar (which I was quite happy with except for the $$$ --- paid $250 for a 125mw, and a few weeks later paid $200 for a 200mw...)
Hope that helps, if you have any questions dont hesitate to post them, somone on here will surely know the answer to ANYTHING you ask about lasers (even labbies)
. The amount of power I am looking for is..... enough to light a cigarette by directing it at the tobacco. Is that feasible? Definitely something with good power. If it is a visible beam, that is preferred. Can I have more info on these IR or near IR beams? I know with a pair of nightvisions we could see the IR beams easily, which would be cool (considering nightvison has a built in IR floodlight you can turn on for BRIGHT illumination at night). I have been reading around about the best lasers out there. I am interested in those of you who offer homemade lasers as well, and would be willing to pay for one of you guys to make one if you are interested ( I have paypal too so it is not a problem ). Thanks for your answers so far, looking forward to joined the laser community in the near future
