I've been reading on this site for a while now as I am building my first laser. And have decided to join in an attempt to learn more about general electronics and lasers. I have some experience with electronics and through reading these forums and asking the all knowing oracle (Google) I've managed to get an idea of what it is I need.
(I would appreciate any input on my choices good or bad and why or why not)
I purchased the following items so far:
This flashlight as the host.
6x SF-AW210 diode in an Aixiz module.
3x Energizer Li-Ion CR123's
rkcstr driver.
(I also plan on purchasing a good heatsink once i get the dimensions of the host)
After a lot of digging around this site and searching Google I've decided a safe current for the diode would be 180mA. So it would be powerful enough to burn but still have decent life.(right?)
The thing I'm having trouble with is calculating the power(mW) output of what this is going to be. I'll have 9V from the 3x CR123's in series at 180mA current. So by Ohms law P=E x I or
9 x .18 = 1.62 . This is where I don't understand. 1.62 Watts ? So .00162mW ? This doesn't seem right. Ideally I would want ~200mW output power. Correct?
Basically my question is, what am I missing?
