i have bought a nice 120mw dorcy from kenom cant wait for it to arrive 130$ beats 400$wikedlazerz i was wondering that when i get some spare diodes ( 3 more) is there a way to up the power goin to the diode without sacrificing the dorcy driver ( these are very good and stable) because i know thses diodes run upto 230mw quite well with a short runcycle and a relativly short endlife ( 200-500 hours)

Well, since Kenom is using the included driver in the Dorcy - you would have to completely re-work the dirver to suit your needs....I am fairly certain it would void the generous warranty that Kenom included in the sale of that laser, too !
oh well ill wait until i get some diodes from the forum GBs and make my own
what driving system / mA would give a smooth 200mWmax with those diodes (3v) Pot in line with resistor and a cap across the diode to stop spikes ( 47nF)? or 47pF
my eletronic maths and diode ma>mw knowlage is quite well Crap
i would be mounting in a custom case with good heatsinks so size is no matter
i only want a singleturn pot and a resistor so i can set it at minimum (5-10mw) then crank it up to max at 200mw
help on the risistances i would need?
of the set risistor and the pot
set risistor and pot at minimum = 200mw pot at full risiatance = 5-10mw

For 200mW you're probably looking at around 300-400mA depending on your diode. At that rate, you really shouldn't expect more than 10 hours of life out of the diode.
Mike could tell you better since he actually tested the outputs of several GB laser diodes.
