Well this may be old news to some but I figured I would post this incase someone hasn't seen it. Thanks to Casio's Green Slim Projectors we now have a cheep source of 1W 445nm blue diodes. Basically the projector uses a blue diode along with a phosphor in order to produce green and a high powered red led. I found some information about the diodes on this website
5.6mm closed can laser diode case neutral forward voltage of 4.0-4.5 volts Original output power in projector: >600mW Forward voltage: 4.0v @ 300mA Threshold current: 200-300mA Beam collimates to a 0.75mm x 4.5mm beam at aperture using Aixiz acrylic lens
I also found some diodes on ebay for about $100 and WL is selling this in assembled 1W pointer form Seems like a good time to start that RGB scanner project I have been holding off on

I own one, very cool :) The projectors run them around 600mA, and thers a lot of people running these at 1Amp...I've seen 1A runs for 40 mins on TEC systems. I, like most others, run them at 700mA I got mine for $50 after shipping, and recently $30
Same diodes are in these, I hope to get mine within 1-2 weeks!

I bought one of those WL arctic lasers. They use these diodes. I figured i'd just buy the ready-made laser because i'd have to machine a case for a diy laser anyway.

I manage to get mine for $196 with the 2 year warrenty :) I got in when it was free shipping, 10% off, and $20 warranty :D
WL claims its a TEM00 laser, but i highly doubt it. These are multimode diodes and make a ---- on your wall. It would be near impossible to get a TRUE TEM00 dot on the wall. And they claimed 1.5mm beam...Just got to wait and see!

Eh, i don't care about TEM. I have a green laser that mode hops and it's quite interesting watching those patterns change when i put it through a lens.

Well, TEM00 is best for long distance pointing / beam. Else the distance you can see the beam at night is going to be short. Personal preferences. Where you get the 250mW green? O-Like? Rayfoss? My 200mW came from rayfoss :D
