No. The voltage is too low, you'd probably permanently damage/destroy the lithium batteries.

I appreciate you wanting to share info, but I would bet that almost everybody on this forum was aware of this already XD.

My setup is just a piece of gypsum drywall sitting on a bicycle innertube on my floor, rock solid even for 15 minute long exposures (I'm just doing Denisyuk holograms, very forgiving)

Asking questions is how we learn. Its not unreasonable to learn about TEA/Nitrogen lasers and wonder if other gases would work.

Yeah I only have a cursory knowledge of gas lasers, but I'm pretty sure argon lasers are a lot more complex than simply creating a discharge through argon gas, IIRC the gain is pretty low so it takes a lot of input energy to get even a small output, not to mention you'd probably need to design a...

Yeah its definitely a labor of love. I've spent a long ass time on this and am only now just barely able to produce reliable results. But the payoff is worth it IMO. Now its just a matter of refining my plate production and post processing to get the quality up.

A few DCG process holograms I've made over the past couple of weeks with my Osram PL530 laser.

Nah, for all its flaws, it was still an impressive thing to have a vehicle that could be re-used that many times. And I still believe had NASA gotten to build their original vision of the shuttle it would have been far more successful and cost effective, but the Air Force got involved and the...

BigClive on YouTube has a running series where he tried carbonating various drinks, most of them dont turn out well lol. Tried carbonating milk once, but the carbonic acid that forms made the milk curdle

If you're just looking for a non-visible laser and it doesnt have to be UV, IR is the way to go. Plenty of cheap and decent options for IR since they get used as pump sources for DPSS lasers.

Sub 400nm at 3+ watts? Nitrogen/TEA laser is the only thing that comes to mind that doesn't cost as much as a decent car. Nitrogen lasers are pulsed though, if you need true CW then best of luck to you.

Its my favorite piece of nerd lore, that "Phaser" from Star Trek is derived from "Photon Maser" (Although to technically since masers use microwaves thats still photons) because "Laser" wasn't a common enough word yet. But in the early original series Phasers were essentially just lasers.

*if* your laser could draw more current then those batteries could supply, then yes better batteries with a higher current output could increase its output power. This is almost certainly not the case though. I would still highly recommend getting good quality batteries though, those cheap...

*Im not a medical professional and this is not professional advice* Buuut, looking at the focused spot of a powerful laser could do damage over time, akin to how exposure to loud noise over long periods can still damage your hearing, even if the noise isn't above the immediate damage threshold...

The light you see as the "beam" is light that has been redirected out of the collimated beam by scattering off small particles in the air. AFAIK pretty much any laser you can easily get your hands on, that scattered light that you see as the beam isnt a hazard, its a tiny amount of the total...

But if it's through eBay/Amazon is the purchasers credit card info even visible to the seller? I'm pretty sure eBay/Amazon acts as an intermediary for the money and that the seller never sees the purchasers credit card info.

Maybe 2$ usd is worth a lot more over there? And they probably churn out so many of those laser pointers at this point they probably cost cents to make.

With good filtering and a sensitive receiver/detector, probably can get decent results. They can reliably bounce a laser off the moon and back and detect that handful of photons that make it back to the detector after all.
