Are there drivers that would fit in such a thing?

I meant IR filter and mixed up wavelength and frequency lol is using the IR pump the only way to get green lasers/a lot of these other colors, or are there diodes that put out each wavelength? Is there a reason that they are such specific wavelengths and not 533 or 531? I mean, to make them...

Oh, I wasn't planning on using that! I was just found it interesting that they existed, is that what they were designed for with the 510 connector? I was thinking more just taking a cheap diode and soldering it to a 510 connector and cutting up a housing I have from crappy ego pen e cigarettes...

I thought the danger of the cheap lasers was that they used an UV source and halved the frequency to produce the violet light? Can't you just use a cheap uv filter?

I was wondering if it would be possible to turn my MVP20W ecigarette battery I no longer use into a power source for a laser? It is variable voltage/wattage (but the wattage only goes down to 6w) whereas the voltage goes to 3.3v. How it usually maintains this in an electric cigarette is it...
