Thanks Kot it's a pleasure working with you ;) The copper bars I have to order for your sinks are getting longer and longer :eg: Oh yes copper is a bitch to machine even with a CNC lathe :( It was actually Blords idea not drilling the hole bore in 12mm the designs keeps getting better and...

Re: Sold: 3+Watt Copper Dominator, 2x26650 blue laser. 3581mW peak ?!!! wtf best result I've seen so far enjoy your copper dominator ;)

The current matters if you drive the diode at 5,5V with a constant current source like a driver at let's say at 1,8A the driver will automatically adjust the forward voltage to exactly the value the diode needs at that current you could even put something like 7V on it doesn't matter on a...

@2,1A plenty, I guess (just guessing) probably 2000 hours or more. ;)

Forward Voltage should be at least 4,6V-4,8V for the M140 regardless the current ;)

mAh is the capacity of a cell and mA(milliAmpere) is an unit for current flow

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.)

Usually the 50mW modules take 300-400mA and the 100mW's 600-700mA

My Ophir 20c Head is underway and I should get it the next few days ;) I showed the current on my DMM in every Build I did !!?

A freak is super rare expect something around 1,7-2,0W

I do not suggest you to buy the 500mW version ! It's way over driven for that tiny heatsink ! Mine died after 4 Hours of use -.- You'd have to live with an duty cycle of 30s on MAX !! I also did an review of this exact laser look at my sig !

With an video camera you can actually see the beam itself from an IR laser But I think 5W of IR is pretty dangerous to play with even for pros ! And it will not burn so well as you might imagine cause no way they are TEM00 my 800mW 405nm burns far better than my 2500mW 445nm single mode...

Great laser I envy you ;) hope I can finish mine soon :P I suggest you to leave the retainer ring screwed on tight ! The heavy copper sink could fall out :)

Re: For sale: 3+Watt Copper Dominator, 2x26650 blue laser. Well ... my glass ball tells me there will be more copper dominators in the future so why not leave the thread open ;)

Re: For sale: 3+Watt Copper Dominator, 2x26650 blue laser. 398,9g to be exact ;) Also believe me the Price is already really tight Blord is not making much profit with this ! Those are CNC made sinks with the highest precision you can get and CNC work is not cheap ! Also Copper prices are...
