Default Re: 7W+ Survival Laser S4X Host w/NUBM44 diode and 4.5A SXD Tutorial

Great tutorial. Detailed explanations and pictures!! I've been out of the game a while but I'm looking to pick up a new 445. It seems a lot has changed in my couple years gone...but this build does not look terribly difficult, and it seems like one hell of a package. I've never done a build myself, only minor repair, but this doesn't seem impossible. So I want to use 9mm? As opposed to 12mm as stated in this thread?

Do you have any more shots of this thing in action? I'm looking for a powerful, bright blue, but I want to see how bad the divergence is on these.

Also you can buy the SX4 with the extended and tapered heatsink and with the heatsink aluminum pill, and DTR sells the diode already in the module with the SXD driver and a G2 lens...so I wouldn't need to pick those up on the side, correct? Just want to make sure I'm on the right track for my first build.

Default Re: 7W+ Survival Laser S4X Host w/NUBM44 diode and 4.5A SXD Tutorial

Thanks Lolvo! The hardest part about this build for me is bonding the driver to the heat sink pill. The thermal epoxy has a very narrow window between liquid and solid and you have to be careful to make sure the driver is in proper contact and position on the pill shelf as the epoxy cures.

The lenses are 9mm diameter, but the diode modules are 12mm diameter.

Those are all the photos I currently have of the laser in operation, I will try and get some more photos as time permits. It is a very bright blue, but the divergence on these diodes with a G-2 lens is pretty high. A 3-element lens would be the easiest way to reduce the divergence.

You are correct on the parts list, but you want to purchase the driver separate from the diode as you will need to trim the wires to length before attaching to the diode. Also, get the shorter back half option so everything will fit. You may want the external lens spring and I highly recommend using high-current capable 18650 batteries such as the AW brand IMR.

Good luck with your build!
