Just forget that idea. The modes of MM diodes are way too close to split them with reasonable efficiency. And you will end up loosing so...

I was also thinking about 1064nm ND:YAG lasers. If we want to have a Q-switched laser, as mentioned above by farbe2 , wouldn't that...

I bought a pulsed 1064nm from I think laser tree? On eBay for 400.00. Does like 10kw peak. Never tried making holes but it can...

Wait a second! Wouldn't it be possible to use a MM laser with a prism* to split the light and then we could isolate the frequency we...

Not really. Currently, the diodes I have are based around trying to get experience with lasers. They're not really practical for...

Maybe I missed it, but how powerful is that ruby laser? I mean, I have no idea how to tell what would work from what would not in the...

I'd look at an old ruby laser. Even a small one will poke such a hole into a razor blade. I made the video below over ten years ago.

The laser that we have selected, BDR209, is designed to be pulsed and at 2x the normal optical output power. I was assuming that we all...

4 inches or closer. Theoretically, I can use a mirror to redirect the beam to another area (for just the laser diode and optics), thus...

At the risk of sounding dense, how do I find the lenses that you suggest? Like what keywords or websites?

Given the parameters you've specified for the material and the size of the holes I think the BDR209 diode may be your best bet. It's a...

Yes. A longer focal will result in a wider beam waist but longer Rayleigh length and vice versa. It’s for that reason lens selection is...

@WizardG , thanks, I should have recalled that. So now I know that I should be looking for a diode SLD3237VF (that's what's in BDR209)...

The main factor is that the material should be fairly tough, while being not electrically conductive. I could use thin paper, provided...
