I try to keep the laser on for 1 min and let it cool down for 30 sec, but I am just keeping om yhe safe side. I've kept it on before for 3 mins and it just got a little bit warm. The focus head is actually jayrob's EzFocus adaptor, I like the look of it on this host.

Here's a vid of the laser burning a toothpick, a piece of paper (actually lights the paper on fire), and a piece of plastic. http://www.youtube.com/watch?v=6TavA5repx4&feature=youtu.be I fail at embedding so someone please embed for me :P

I built this little guy last week before flying out to New York. Now that i'm back, I had some time to take pics and make a video. Basically I had this host lying around for a while, and after getting back into lasers, I decided to build a 445 out of it. The heatsink is a direct press-fit copper...

Also, depending on the type of diode (open can or closed can?) I would run it anywhere from 200-400mA

You answered your own question. You connected it directly to the battery which is why it died. You need a driver to regulate current, or at the least, a resistor.

I have definitely considered that possibility, but it has to be. My only 6x diode LED'd on me a while ago, and the beam profile of this one is exactly that of a PHR.

You said it! This new generation of laser hobbyists are spoiled! :P This kind of power a few years ago was UNHEARD of for PHR diodes, and you'd have to spend $200 on a 6x burner to get that kind of power, and even they weren't as efficient as this PHR I have :O

First, some background info... So, as many of you know, i've been out of the laser hobby for a while. A good two years. All this time I had a PHR-803T diode laying around. What got me back into the hobby, was my buddy going camping, and asking me if I could build him a laser to take along. I...

Awesome laser, Bill!

Check out the thread in my sig! And for max power from a 405, you'll want a 405-g-1 or g-2 lens.

Re: 1.2W Blue-Ice Lasers $120 shipped These are beautiful, Yobresal! How long will they be available for? I might have to pick one up myself!

Then it's probably not your driver... If it is a low quality multimeter, that is probably the cause. My first multimeter (some generic chinese one) did the same thing.

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please Interesting...

Sounds like there's something wrong with your pot... Do you have any different drivers on hand? Use one with the test load and see if you get consistent readings.

Bump.
