The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.
I was wondering for my knowledge and for others if people who have removed the DVD diode from a drive what model has the highest power output? I was also thinking of getting a light scribe drive as I think the laser burns the image onto the disc probably it has a very high power output.

I don't know if lightscribe drives are expecially strong or not, cause I never found such a device as junk, but I guess it wont make a big difference. The image is not burnt into the disc, the disc has a special coating sensitive to the specific laser wavelength, making it change its color. Actualy just the same thing as used for the "data side" of the disc.
The key here is writing speed. The more speed the faster the DVD has to spin. If it spins very fast, the exposure time to the laserspot gets shorter, so the laser has to be stronger to make any effect.
thanks I was thinking of getting a 18X DVD and 8X DL speed samsung drive because the faster ones have the flat laser package not the can. I will be mounting it with a collimator lens. do you think it will be a powerful laser for burning/cutting/etching plastic?

The power available from a dvd-r laser is directly proportional to the drive speed--so the faster the drive the better.
You aren't going to burn anything with a dvd-r laser, although when focused it is very possible to etch plastic. I have also heard of people using them to fuse finely ground plastic to make 2d/3d structures. If you want to be able to set things of fire your really want to have at least 10w of power available (CO2 laser would be ideal, although it is possible to get fiber coupled arrays of diodes for almost reasonable prices on ebay--just don't get the bare diode bars as they can't be focused worth a crap).
thanks I may work on a CO2 laser though the tube is verry expensive and would be very hard to make. I just ordered the drive and I did reaserch and It contains a 280mw red laser diode in the 9 or 5 mm package can.

I can make you a CO2 laser tube for very cheap - it's not as fancy as the $500 commercial tubes, but the last laser made with one is still welding titanium body jewelery 3 years later, so it must have worked. PM me if interested.

You can get brand new sealed 10watt c02 laser tubes on ebay for 199$. I dont think you will be making a successful c02 laser for cheaper than that. All you need is a HV power supply(your deffinately in the right place for that )
As to DVD lasers for burning, why on earth do you want a DVD laser?You can get a diode laser producing many times the power of these DVD lasers on ebay. Ive had 2 watt fiber coupled diode lasers(IR) than QUICKLY etch.
