Hi,

This is a 24x DVD burner. Anyone with exerience with the laser inside, or similar lasers?

Well it is probably LOC diode, like any other >18x burner...

We did this when they first released them....i bought one for $30 or so......it's a flat plastic diode (like the ones in the LG 8x BR drives)

Thanks. If it is the flat one, which is the same as in LG, I have already had some experience with that one. The beam is slightly oval shaped, and not the typical rectangular shape you'll find in other laser diodes. This means that ALL the energy is passing the lens, even if the focal length is relatively long. The dot shape is pretty close to a gaussian TEM00.
I soldered the metal base into a brass YAG chrystal holder. very good cooling and worked great. I used that one in an optical trap I made. The optical trap-videos are here btw:

Holy cr'p. optical trapping... I've never heard of that! From what I have seen, it appears that a tiny particle is being held by electromagnetic wave (light), trapped by the light itself. But it's just my wild guess...
Looks totaly awsome! Laser needs to be focused very close to that, right?
I'll definetly try that out, when I get home, with a red laser with glass lens.

let me know if it works....

Don't work with my glass lens and loc at 400mA.

I found another 24x DVD burner: Newegg.com - Sony Optiarc Black 24X DVD+R 8X DVD+RW 12X DVD+R DL 24X DVD-R 6X DVD-RW 12X DVD-RAM 16X DVD-ROM 48X CD-R 32X CD-RW 48X CD-ROM 2MB Cache SATA DVD/CD Rewritable Drive - CD / DVD Burners

So the diode in this burner is most likely one of the 3.6mm (small open can) diodes, like the ones in 8x Blu Ray drives?

Don't use too much power. Reduce it a bit, and find a black plastic piece. The focal length can be as far as 1 inch.

I managed to did it with like, 3 cm foca lenght. Full power LOC though!
The trick is that you should attemt it in completely draft free environment, you must not breathe on it even!

ReNNo · 12-05-2009, 08:09 PM

Yeah, trick is to keep breathing.
Any air flow will blow the particles away.

You mean, 'NOT' breathing

But hell, it is difficult to acomplish that optical trapping. Taking every care that I don't breathe, and got no results.
Once I managed to get something, I said something to my brother, but I talked so I did cause some airflow on the particles, but they stayed there...
