Congratulations for scoring that Beam expander beauty from Thorlabs Nubb13 is a very interesting diode. Would like to see if you are able to knife edge is successfully, since the distance between the individual laser diodes is even tinier compared to nubm35/31. Must be challenging. In terms of...

BTW guys, I would greatly appreciate if someone could suggest what can be improved about this design. Would you like more watts (overclocking the nubm35), more battery life, beam expanders? Any suggestion is welcome. Thank you in advance

Hi RedCowboy, Yes, exactly, It comes down to the size of the convex like you said. I bought 8 convex and 4 convex lenses of different magnification powers and after running all possible combinations came to the conclusion that there is no significant improvement of adding a beam expander to...

Thanks Thanh! Took a lot of time to design and develop

Glad that you like it. My fingers took a big gamble in order to make that shot. :)

Hi, I would like to offer an aluminum host made of 6082 alloy for great thermal conductivity, that can be used to make 70.000 mW portable/pocket laser using the NUBM35 and 2 Lipo Batteries. Full Free instructions as well as purchasing link here: Truelasersaber.com You can see some cool tests...

Hello to anyone interested in NUBM35 portable laser. Wanted to share some information that might be useful regarding this topic. I manage to build a sexy looking version of NUBM35 portable laser inspired in the design of StyroPyro and with the BIG help of Giannis_TDM. Big thanks to both of...

I have something useful to add to this conversation. I was planning to combine two Nubm31T using dichroic cube. I though that by spinning the laser diodes I could change the polarity and manage to combine them, but after some tests that I made, I came to the conclusion that it is imposible...

I will do that too, just in case he does not read the direct message. Thank you once again for your time, and apologize for the initial controversy.

Здравей Борка. Да, от Русе съм, ама админа ми изтри поста. Каза че е "БС"

I would like to know more about this topic...

Great stuff. Highly recommended

Yes, Francis is very responsive

I do think he is legit

I am interested in the RGB of sanwu too.

have anyone tested the 20W Nubm13?

Yes, styropyro is awesome. Got hooked to lasers 10 years ago due to one of his first YT videos.

The numb35 are much smaller and twice as powerful The brand new 20W nubm13 are 10% of the area of a Nubm35!

Welcome. Noob here too :)

This laser diode is a beast! would be nice to combine 2 of them for extra power
