Technically yes it is possible to get different coloured light out of a laser device, but you are not changing the color of the diode. This process is called DPSSL. They usually use a high powered 808nm IR pump diode for this process, so unless you have a diode of this wavelength and the means...

Can you link the driver and diode you'll be using?

Looks like everything is glued, won't be getting anything apart without destroying it unfortunately. Oh well, shame because its quite a nice host with a lot of room for optics.

Hello LPF, I hope you are well. I've recently been given a broken Thor ultra and I'd like to fit a new diode and some lenses to it. I've done some research and it seems like a generic host imported from China, but I can't seem to find any information on how they're put together or come apart...

I'll definitely have a look into this, thanks!

I can't see any blue light through these glasses though, the dot is entirely red/orange but its extremely bright. Surely if light was getting through it'd be blue still right? My 15w 445nm engraving laser doesn't seem to have this problem, only my 2x nubm44 build. Which I find rather strange.

The c6 accepts either 2 X RCR123A, 2 X CR123A or 1 X 18650 I'd go with the 18650. This depends heavily on what diode you'll be using and the voltage it requires, 18650s are 4.2v when charged. My fav cells are the Molicel P28A's. They handle up to 28A discharge which will be way more then...

The 7w (Only 1 out of the 2 NUBM47s powered up) looks identical to the 2nd photo you sent, its a small red dot that is only just visible. The 15w (both on) looks similar but its a much paler red, almost an orange and is EXTREMELY bright. I thought maybe some other wavelength was being generated...

I thought that originally, but that'd mean the 7w dot would also be pretty bright too. The 7 and 15w dots are night and day difference, the 7 I can barely see and the 15 hurts my eyes to look at. So I'm not too sure what's going on here tbf.

Hey! The dot is the same colour as the safety glasses. I originally thought maybe a different wavelength is getting through but a single Nubm47 doesn't do this, so I'm confused as to why its happening with 2 of them.

Hello all, I hope you are well! I've just finished building my 15w 450nm beast based on 2x NUBM47-V2's and I noticed something when looking at the dot through my laser glasses, it was visible and quite bright (The glasses are 190-540nm OD6 from survival lasers) I decided to enclose the laser...
