Greetings Folks!

While I know many of you have already accomplished this, I'm proud to say that I've now broken the 2W barrier. 1.9W was my most power laser until last night, but after completing this it was goodbye 1999 all over again! With this project I wanted to use a larger host for heat dissipation & since I'm very picky about lasers not looking like flashlights, I recently came across a few larger ones that seemed cool enough for making lasers from them. Of course I documented the process to share with you, have a look! :D

The host - Cree SacredFire NF-582

Parts - NF-582, Jayrob custom polished heatsink, 1.8A Mohgasm, H1600 445nm,
405-G-1 lens, 2x18650 Batteries (not pictured)

Mohgasm driver, H1600 diode

Aixiz module

I use flaminpyro's diode press for its incredible accuracy. Pressing the diode
absolutely level is important to me, otherwise the slightest angle or offset will
result with a crooked beam

Slightly flush, completely level

Soldered leads

Heatshrinking the leads for stability & protection

Massive aluminum heatsink

Heatsinking a 1.8A driver is absolutely necessary unless you want short runtimes
or to burn out the driver. I plan on sinking this driver to the back of the larger
heatsink that holds the aixiz module. To do this, I'm cutting small pieces from a
strip of black aluminum that came from a computer graphics card heatsink I took
apart. I have a dozen of these aluminum strips & they work outstanding to use for
heatsinking hot drivers

016-1.jpg


I'm using a generous amount of thermal compound so the heatsink doesn't short
any components on the driver

017.jpg


30 minutes to completely dry

018.jpg


The heatsink is sitting on enough compound to prevent the driver from shorting out
on the larger heatsink it will be mounted onto

019.jpg


Another heavy layer of compound for mounting onto the larger heatsink. I use a
thick layer here for efficient heat transfer and to leave enough room to keep the
driver from touching anything

020.jpg


Mounted on the large heatsink

You can see nothing is touching or shorting anywhere when bonding these parts
together

023.jpg


Soldered the diode leads
025.jpg


Soldered the battery leads
026.jpg


Making sure the solder joints don't touch the massive heatsink

027.jpg


An additional heatsink on the top of the driver was added for extra heat dissipation
028.jpg

After everything dried I mounted the heatsink into the host & screwed on the crown.
Here's what it looks like inside

041.jpg


030.jpg


I stripped everything off a cheapy 17mm chinese driver to use for a contact board
031.jpg


I inserted the leads through the pill

033.jpg


Soldered the positive lead & left the negative to mount inside the pill
032.jpg


Attached the contact board to the pill

Screwed in the pill

037.jpg


Added the 405-G-1 lens and it's done!
042.jpg


Immediately I needed to test this on my LPM to see how much it had
043.jpg


2.1W :D I was very happy
044-1.jpg


045-1.jpg


My first 2W laser, a success! Now the obligatory first 2W beamshot of course...
050-2.jpg


I've ran it so far for about 3 minutes before the host starts getting noticeably
warm. Overall I am very happy with this build. :D

Thanks for reading and checking this out folks, let me know what you think! :beer:

Great work. Like that you took the time to document the process.:beer:

Thanks man! Covering the process like that seemed necessary too, it seems helpful when there's pictures to look at how it's all been done :beer:

Nice detail review. That big heatsink will keep the diode happy.

Thanks guys!! I plan on building several more beasts like this soon & documenting those processes as well. It's good to hear these pictures can be helpful for other people looking to do similar builds, especially knowing that I've enjoyed the same benefits from senior members' tutorials and builds that were documented much in the same way. :D :beer:
