New LASER Power Record on my LPM?!? | LaserCube Ultra 750K Subs Special

Time to beat my all-time laser power record! The latest and largest LaserCube should be the strongest laser I have ever tested. I will use a laser power meter and spectrometer to hopefully verify its specs.
I will also open it up to see its inner workings and figure out the laser beam paths inside it. Quite complicated! This also means I can include instructions on how to open it up - for example to change the rechargeable battery after years of use. Perhaps the first time this has been published?
Anyway, this was meant as something special to celebrate reaching 750,000 subscribers! Thank you so much!

Stunning video you did there (as usual!). Thank you for opening the Cube! Your calculations, meticulous measurements and describing "what's inside" were top-notch, totally! I think we have to start working on 10W LaserCube to celebrate 1M subs with you! 😁

Thank, Tim :) Much more to come.

[@Zenodilodon]

Thanks for the shout out! Looks like the laser head might be manufactured by OPT. Very glad to see that there is a glass plate installed in front of your reds. Those are probably open can and I have seen those glass plates be a savior for open can reds. That is a bit of power in a nice little box. I don't recognize the galvos, any markings on them/the amp? Excellent video, and review! Oh, one interesting thing to try with your higher power laser. Hang a black piece of thin fabric up and can the laser on it with a pattern. You should clearly hear the laser firing on the fabric from 2 foot away!

[@Zenodilodon]

Also, a slight correction to your understanding of the lenses. You're partially correct, however the fast axis correction is normally on the laser diode, I think they are on your reds. The 3 optics after the laser diode/FAC that you see kind of work like this. The first lens is there to allow correction by shifting the collimating point and angle of the laser beam on the horizontal axis. The last 2 lenses are the collimating lenses, one for horizontal and one for vertical. Since the focal point of the horizontal output has been shifted the collimating lenses per axis can be done with lenses in different spaces from the laser diode. This break of the 2 axis allows for various trade offs like having a thinner fast axis for the knife edge mirrors with I think slightly more divergence VS the slow having a wider beam at the start but lower divergence overall. With cylindrical lenses the real trick is to think of a single laser is behaving like 2 independent ones in the same space, or at least is does for me. It's actually astonishing how well these lenses collimate multimode lasers diodes. I might be a fan of good old spherical lenses, but they limitations in flexibility.

[@SilesiaLasers]

I love your videos! And seeing LaserCube 7.5W Ultra (which is also a part of my laser equipment) was terrific! Keep it up!

@brainiac75 I just wanted to say thank you for all of the content you make. My field of study was electrical engineering about 100 years ago. I have never worked as an EE, so your content is the only exposure I have, so thank you very much. Keep up the great content!

Great video! Amazing optical design!!! Congratulations on reaching so many subs! Always loved your vids from the start. I would love to see some vids about HV or just electricity as a whole. Get yourself a large HV transformer, and pull some huge arcs :) You could also measure the spectrum of the light produced, and see how it varies with electrode material. You could also talk about power factor, resonant capacitors (and LC oscillation in general), among other things!
