Input of X volts to have output power = 30mW?
How many mW is 3 volts? Additionally, how many volts is 30mW? Also, what is the volt/mW ratio?
You see, I have a class III laser with a max output of <30mW (wavelength = 532nm +-10). It's running on two 1.5V AAA batteries, and I'm sure I can kick the power up quite a bit. I just don't know the conversion factor.
Already Googled, didn't see anything.

Re: Input of X volts to have output power = 30mW?
Alternate title: HEY GUYS HOW DO I LIGHT JOINT WITH LASER? Clearly a noble endeavour, and don't say you haven't thought it.
I don't actually have anything constructive to add, so uh yeah.

Re: Input of X volts to have output power = 30mW?
Not me desired intention, as I do not have any papers... Or any weed atm.... lol but not a bad idea.
No, in fact, I just want to see how high I can make this go up to and see what all I can burn/pop.

Re: Input of X volts to have output power = 30mW?
A watt (the W there) is not a unit directly convertable to volts unless you also know your amperage. Watts = Volts X AmpsBut, if you know the max voltage rating for your diode, then you can try increasing the amperage after getting that many volts.

Re: Input of X volts to have output power = 30mW?
I don't know much about this, but from what I remember it's some bull♥♥♥♥ about if you have amps aswell, you can calculate out the voltage from watts.
Or something like that. I'm not supposed to know this for a year.
DAMNIT DUH

Re: Input of X volts to have output power = 30mW?
Code: function voltage() V = voltage W = wattage A = amperage //formula V = W/A
if V = W/A then V*A = W V/W = A end end

Re: Input of X volts to have output power = 30mW?
If you mean amplitude, then you are completely correct. I have no idea what kind of amplitude that thing would run at normally, though.

I'm pretty sure it's called watts, not wattage

@Roast Veg: No, it's amperage all right
@Lizard: the quantity of watts is known as wattage

Definitely amperage, and definitely wattage. Edit: What Joe said, the blasted ninja.

Hmm... I think it must be one of our British-isms. [Hahaha here we make fun of Americisms]
Anyway, I see Watts as a foolish term anyway. I say whack up that voltage and see what happens.

Re: Input of X volts to have output power = 30mW?
I'll try to find a link of my exact laser. Hold on. *EDIT* This, pretty much: http://www.dealextreme.com/details.dx/sku.12337Also, no idea the # of amps.

Re: Input of X volts to have output power = 30mW?
Well if you said: Watts = Volts X Amps And my max output is <30mw, and my volts i know is 3, can I find my amps? Also, I REALLY doubt I can change the amps. All I can do is change the volts. The laser is encased in metal.

Re: Input of X volts to have output power = 30mW?
And if you had a high voltage but a low amperage, you would have a very weak laser beam that lasted a long time.
