Hi I have done tons of research about building my own etching laser. But when it comes to the laser I have on hand I have no idea how to go about this. Also I cannot seem to find the details about this diode. All I know is that it is a IR laser in a working Pioneer ld700 LaserDisc player. If anyone can help me with how I should go about building this etching laser I would be eternally grateful

Typically, the diodes in disc players are not powerful enough to etch with. I didn't look up this particular player, but that likely still holds true.

What Paul said ^^^
Pretty much a waste of time for many reasons. Much better to purchase a low cost etching/engraving module on eBay

"Those lenses in DVD R/W devices are adjustable, but because the focal length to the DVD is so short, they are unusable for this purpose. They have to focus down to ~1000nm to read or write to the DVD, IIRC. The polymer used for the DVD has it's own refraction index too, so the overall distance is very small.

Use LPF search to see other threads about same---search "DVD diode etching engraving" many threads concerning same.
