Hello, it's first time when I post în this forum, I want to build a laser for cnc or laser show ( xy ilda), I want to run nubm44 diode at 4A, to have a long life, also I built a Massive Heatsink 40.5x66x77mm, în thickness (40.5mm), I'll give a 25mm hole to put in a copper module from dtr lasers, over that pice I will put a cpu pc heatsink.
Some time ago, I build a laser with nubm07e diode, very beautyfull color.
But this nubm44 I really want to live a long time.
Do you have any suggestions or opinions about this build with big pice of aluminium?
I read about this diode, he has few problema with internal lens, he drill a hole in lens, something happened this bad event with nubm44-81?
I would like to make long cycles with this heatsink and 4A, it's ok?

A friend got this, it's a glass în diode, It's not about focusing lens.

Hi, If that lens was seated on that diode and broke Be careful now for that diode is an open can and is very touchy win dust and dirt. Or the diode will fail fast. What diode is that wave length and output .. You need a good host that can hold a 9mmx 0.5 lens thats focusable . but you will need a heat sink machined to take it . As I do all machining to this specifications ...
