That looks sleek massive big awesome host. I am sure a heavy laser could be build.
Okay thanks. So what would the correlation be between the number if amps and the duty cycle? (Just so that I can get a clearer idea for future builds
I'm afraid I cannot give you any firm formula for it, it's more of a "gut feeling" from experience from working with those things.
It's like if you've ever asked a cook how long does something take. "Until it looks about right".
If you really want to calculate stuff, the heatsink's mass if aprox. 60-70 grams of aluminium, diode's thermal power output is aprox 10 Watts and it's maximum case temperature shouldn't exceed aprox 150°C maximum, with 100°C at all times should be preferable.
Reflow soldering happens at 180°C IIRC so by the time you get there, your laser's diode's die would've desoldered from it's pedestal.
