its pretty mess in the inside , just wanted to know the opinions , I am a newbie and this is my first build , burned more than 30 laser-diodes before that was done
dvd-burner laser diode
You can always use computer heatsink and drill hole into it.
Everyone has to start somewhere. Good job. How did you go through 30 diodes? :thinking:
Depending on how much power you're giving the diode that aixiz module will not be enough heat sinking and the diode will burn out.
please i would like to learn more , would that be the best heat sink ? and what part of computer are you talking about ? you mean the cpu ?
would this method make me able to run it at it maximum power ?
If you open up a dead computer, there should be a square heatsink (2 or 3 inches across) on a board, on a large chip that runs the entire computer.
If you don't know what I'm talking about, watch this-

With proper heatsinking, you could run this laser at higher than 400ma and get about 250ma output, and keep the laser on without following a duty cycle.
I use these heatsinks for my DIY builds.
I drill out the center with an 11.89mm drill bit (closest thing I could find to 12mm at home depot) and then put the AIXIZ module in the hole with some thermal epoxy.
This big of a heatsink would only be necessary if you want a laser with no duty cycle and even then it's a little big. When I use the included fan I'm able to run 445nm diodes at 1,600mW for hours without a problem.

that's sooooooo cool !! , this is very helpful , I really appreciate your reply
but I have a couple of questions regarding this effective heatsinking method , what if I reshaped that heatsink so that it fits in my housing , would that affect the heatsinking ? (as I realize ,after all, this heatsink is much more bigger than what the laser needs to cool down)
another question is , would I be able to run it on 500 mA ? and if I did , what would be the power that my laser would produce ?
I don't understand how exactly the laser diodes work in addition to what is the amount of power it produce related to .... , we learned about diodes in my electronics class , but i guess the Prof have missed the ld's part...
,, and again sorry for my bad english
thanks
and sorry you meant giving it 400 ma so i get 250 mW as an output ?
dude !! 1.600 mW is so cool ! Where do you get such a diode ? what is the lens used ? how do you get such a power ? , at what cost ?
your so lucky to have that thing ! I guess it can burn WHITE things from 4 meters away right ? , by the way ,what is duty cycle ?
hope you answer me these lots of questions , thank you anyway
