We're in communication - thanks. In the meantime, I'm still taking offers.

Okay. So I'm decided on a 5mW 830nm 500ms pulse/constant handheld unit. Let's simplify everything just to get this done and I'll see if I want to order more later. From what I'm hearing from you folks this sounds simple enough. I simply don't have the tools to make it myself. Who would like to...

It doesn't say the spread on it. Is it possible that the spread would go that far (up 5nm)? Or would that, like, not even be a laser? Lol. Could I just make sure only too use it when it's against the skin, especially on 10mW mode? That would make it safe, no?

Um, yes. I'm offering to buy more than one. Lol. I'll have you know what we are piecing together here is my dream-laser for photobiomodulation. Just sayin'. If these could be mass-produced and I'm satisfied with the product I may even invest or team up with the builder. If you are catching what...

Lol, excellent. I've learned a lot from you folks already. Thanks.

Good to know. I don't even really know what you mean by "beam specs" but sure! You are correct about point blank range. As I've said before, I get great results with a 5mW device. A class IIIA laser is the basic model purchased by most practitioners for basic low-level laser therapy. 10mW...

I can randomly select some laser diodes, sure. But I have no idea what the other criteria are for selecting a good diode. You all have the knowledge of what diodes to choose for what, etc. The only parameters I'm looking for specifically are the wattage (5-10mw) and the wavelength (835nm). And...

I singled out specifically these wavelengths because they are the peak emission and absorption spectra of the copper A protein oxidized and reduced in mitochondria. So I think it's fairly specific based on some of the spikes you can see in that article. For instance the 715nm is based on a...

Fantastic. Can it be done with perhaps 4 LEDs, close to the wavelengths I mentioned above (605, 655, 715, 835)? And yes, I'm talking about a separate unit. If this can be done easier, cheaper, and quicker then I may forego the laser unit for now and try this out first. If not then an 835nm laser...

YES! The laser-people assemble!!! You guys rock. :cool: To tell you the truth I currently use a small, 5mW 635nm with great results. And yes, there's good reason to have focus and good reason to have a spread as well. I wonder, could a laser tip be added to only allow the LED light out through...

Very cool, thanks. How about the kind of casing that would be used? Can some LEDs fit into the tip of it? Sorry - I hope it's not absurd to ask you laser-builders to build something with LEDs, lol. But for photobiomodulation having a broader range of frequencies has advantages. Just a thought...

Yes! Thank you for the clarification! I will stick with saying 500ms and 1 sec. I am now in the market for TWO of these same lasers, possibly three. I will know if I want a third one by Wednesday. Any takers?

I'm going to be doing photobiomodulation on myself.

No - I will be using these for myself to experiment.

Hi! I'd like to commission someone in this community to build me a device. I'm looking for something quite weak by your standards. The minimum I'm looking for is a 5mW pulsed 660nm (maybe, currently undecided) handheld unit that can switch from a constant beam to a pulse every 500ms (also...
