I searched on Ebay like you said, and i found 1 aixiz collimator `12mm Aixiz Laser Module Focusing Tool Axiz Diode 5.6`. It looks like a metal tube and i cannot see a lense. Shall i buy this item and do i have to buy an extra lens for it? The item number on ebay.com is 280345481688. My laser is a red DVD laser. Can you guys check it out for me? Cheers

I'm fairly sure of it. From what I gather the PHR-803T sled is a replacement sled for the Xbox 360, so any blue diodes you find in a 360 will probably be very similar. Karol has a bunch great info on these diodes.

Yes, the PHR sleds are from the HD DVD drives.
I bought about 6 sleds. If you are looking for a driver, you can get one from
It's a boost converter, and runs the PHR diodes (Forward voltage of 5V) perfectly off a 3V source.
You can also buy the "Aixiz" modules from the page aswell. The plastic lens ones are recommended for 405nm lasers, glass fluoresces with 405nm light :)
I have one running at 100ma with the flexdrive and it barely gets warm, and I am going to eventually build it into a barrel from a Wicked Lasers Core.

Conundrum wrote ... is this the same diode used in the HD-DVD xbox360 sled?
Yep, the diode from this thread is from Xbox360 HD DVD drive. You can find two different laser modules in these drives: PHR-803T which is the one described here, and DT0811. Diodes from PHRs are considered to be more powerful. I've had several diodes from these drives and haven't seen DT0811 one that could stand more than 120-130mA (every diode from DT0811 should stand 80mA I think). PHRs can sometimes stand even about 320mAs (I had one that could do it), and I think that every diode from PHR can work pretty well at 150mA. You can find A LOT of information, also power vs. current charts, on .
I hope you all aren't paying anymore than $10 or so for your PHR sleds...
Careful with Ebay laser sellers.... they feed off of their consumer's ignorances and will attempt to sell a PHR sled for much more.
The PHR has always been a tough little diode. They HAVE been pushed to high currents, but this greatly shortens their lifespan. The PHR is considered a 60mW CW diode.
Since this diode is very efficient, we can feed them about 120-130mA safely for long lifetimes, as well as retaining their burning capablilites. At typical 120mA PHR can light any match in less than 1 second. It can pop balloons, and even cut throgh white paper if focused properly. At 120mA, a typical PHR should output about 110mW.
At 405nm, its light is deep violet light. It is NOT UV. UV is begins < 400nm, and it technicially not visible. Since this is a laser diode however, there is still a plus or minus 10nm on the diodes actual wavelength.
405nm light will make light colored objects glow. (Theres a name for it, but I can't remember it at the moment) It makes objects behave as if they are under a blacklight. You can 'write' with a sustained glow on just about any glow in the dark object with this laser. The focal distances on these are shorter than they are on red diodes, so I definitely do not recommend reversing the lens to focus the dot. The best colliminating lenses available for blu- ray diodes are currently from the aftermarket realm. (If you wish to know where, I can show you).
Driving diodes is as easy asusing an LM317 as a current regulator rather than a voltage regulator. There are ways...
Right now, if you'd like to feel the burning power of 400+mW of 405nm.... than I recommend buying an 8X blu- ray burner drive. These diodes can burn through CD cases with a 3mm wide beam.... unfocused! Keep in mind, that 12X burners have just been released in Japan.... its rumored that they contain about a half watt of violet inside!
ALWAYS wear safety glasses! Know that any laser >10mw can not only permanently damage your eyes, but can do so instantly. There only needs to be a few microseconds of this much power across your retina to leave a nasty blind spot in your vision. Buy glasses that are only certified for their safety, and for the color range that they protect against.
For any questions or information about whats and wheres.. feel free to PM me. Lasers are one of my specialties!
