Hello everyone, i just purchased a 100mw rated Green laser module from AptLighting. Here are some pics:

AND the pins:

My question is, what is a cheap driver that i can get that can be preset with the correct output for this module. Also, what Amperage would i use for a 100mw module? It looks like it has an acrylic lens focused to infinity and some glue holding it in place. :thanks:
 





Huh, it looks like i got ripped off actually. In the description it says the Max input current is 360mah. Thats means its probably like 75mw max right? Thats still fine for my purposes

Anyways, where can i get a cheap but reliable driver that can supply that current?

Don't confuse mA with mAh ;)
Depends on what input voltage you're planning to use (1 or 2 cells PSU etc.)
If you want an cheap but reliable driver I'd use a linear one (Lm317 etc.)
 
keep in mind that the manufacture puts these limits on many diodes but doesnt mean that we dont push these limits :p
 
mAh is the capacity of a cell and mA(milliAmpere) is an unit for current flow

of it says Ma, not Mah, whats the difference?

Try to use the correct casing. We're referring to a milli-ampere. You've just reverenced a million years.
mA = milli (one thousandth) amperes (amps)
Ma = mega (one million) years (abbreviated "a" and taken from the latin word annus meaning year.)

Ok so if the max input current is 360ma, what do you think the MW will be for this module?
 
If it were a true 100mW then 700mA from a AMC 7135 driver (2x chips) would be perfect, you could run it with a single li-on, minimum heat, and continuous positive. I a "100mW" module from a dealextreme pen running at 700mA in a C6 for about 2 years now..
 
OK, got it, but if the max input current listed in the product details is 360ma, then what kind of power output am i looking at?
 
See HERE

Even though it says 360mA doesnt mean you have to follow it. we push diodes all the time and they live. diode life span is something like 10000 hours at recommended current, even if it drops to 5000 hours when you push it, do you really care?
 
So if i push a diode with the recommnded current at 360ma to, say, 600 or 700, what kind of lifespan am i looking at? Especially if i use short duty cycles?

EDIT: oh sorry, didn't see that earlier post...

ive never used this module before so couldnt say exactly. like any diode it all depends. two people with the exact same diode and exact same driver at same current can get two different results. one could die in 5 minutes while the other lasts years. lasers are funky like that
 
Tru dat. What do you think my chances would be (of NOT failing) pumping this diode at 650ma?
