How good is your health insurance; and if you're selling kits, liability insurance?
Selling kits? Health insurance?
No, and health insurance is up to you.
This project would discuss applications, diode wavelength, power needed, wand design, optics, holders-fixtures-jigs, control using an MC, safety, etc. It would be on you to source the parts, aka "DIY".
As example, pinning smd resistors to an sma connector when making precision Rf load module. Another could just be melting solder paste on items where soldering irons and ovens can't be used.
I don't know yet what the power requirement would be. 1w in 1mm
2 area is quite a bit different than 1w in 5mm
2, power density, etc. So actual power needed really depends on the target spot wanted, but I see many of the commercial systems will use 1mm
2 as the target area for delivering optic power.
