Most transceivers I've seen in a datacenter environment have been under about 20 mW-- assuming they use lasers at all (many low cost MMF 1G or 10G SR optics use IR LEDs instead). Multiple orders of magnitude difference between that and a 60W pulsed laser. Many techs will even try to look into the end of a LC or SC connection for light with their phone's camera (only works for 850nm)... lol

This is great video! I've been using Monport Laser for several months now, and I've been amazed by its versatility. While MOPA Fiber Laser Engravers can handle a range of tasks like welding, cutting, cleaning, and coloring, Monport Laser takes it a step further. With Monport Laser, I've been able to tackle not just engraving, but also precise milling tasks with ease. Its intuitive interface and robust performance make it a standout choice for various applications. Whether you're working on intricate designs or heavy-duty projects, Monport Laser delivers exceptional results every time.

The internal pressure to buy a MOPA rises every day. Marco being the main culprit. I am super interested in seeing more tests with the lithium batteries. How long does it take to get a weld going? With welding the cells its all about limiting the heat that goes in the guts of the cell (besides not melting the insulation) so wonder how it stacks up against spot welding. This multisecond weld is definitely worse, but if it takes little time to weld a fraction, you could swap between cells while welding a larger pack. With spot welding 21700s around 30 Joules seems to be enough for a single good weld on 0.15mm nickel.

I guess a big problem is ensuring every piece of nickel is clamped to the respective cell. A whole nickel strip would be much harder to hold with tiny magnets (even if you managed to avoid demagnetisation with shorter pulses). Could maybe be overcome with some type of clamp... But for safety that would have to be something you could set and then put into an enclosure.

Another fun thing to try is running your 60w with offset fills, roughly: 750mms 60khz 24% (depending on lens size) 200ns 0.03 line spacing (assuming a f160 110mm lens) Adjust power as needed. The desired finish is a light frost, so this is basically a glorified cleaning pass with most of the work being done by the offset fill path. This should work on most metals. Try to start with material that is smooth and clean if you can. You can do some pretty fun optical illusions.

I really like that you can take it off, it has that add on cone thing and then use it as a rust remover or for metal reconditioning, or move the laser to the work instead of bringing the work to the laser.

Great Video :D Love that flexible exhaust setup, I hadn't even thought of something like that- I'm sure I'll be making use of something like this in the future, just not sure exactly how yet.

My disability is not visible, so I don't have the same issues as you, but I understand your struggles. I have oftentimes considered an exoskeleton design over the past 3 decades. If I may offer two ideas 💡 for your consideration:1) Consider all possible modalities of kinetic machines and their dynamic pros & cons. If you could find or build a small Hydraulic pump paired with some Hydraulic actuator/s and work out the specific kinematics for your use case, well you can't bet the power. 2) Electric linear actuators will also produce much more mechanical force. (Though they are often too slow, so you will have to pay close attention to sourcing an appropriate motor and gear train.)

I have been pondering the use of a cheap IR laser onto black perspex or other suitable material that will make a smooth semicircular bottom groove. Making a special machine that has an end effector with angle and radius axis attached to the end of a positioning stage might make the highest quality scratch holograms. Instead of a laser using an preloaded air bearing and marking with a tungsten carbide or sapphire sphere on a spring loaded pin that is pressed into the plastic substrate with a micrometer Z axis would provide dainty lead in and out to give better line fade.

That’s amazing that you can cut 2mm steel! I’d wondered if these small MOPA lasers could handle that.

Here’s a (kinda dicey) thought: What about not an air assist but a slowly-flowing oxygen atmosphere? It’d likely be pretty dramatic, but I wonder if burning the metal bits as they come out would help? (Or would it just more rapidly clog the throat of the cut with iron oxide?)

Have no expertise in laser-oxidising stainless for coloured engravings, but wondering if it's possible to derive the settings semi-automatically with a known test field and a high colour-accuracy camera? There'd still be small variations within the material ofc, but if there is a known relationship between laser 'strength', oxide thickness/texture, and resultant colour, then would an automatic calibration routine be possible? Save time and material, I'd think, but maybe there's too many variables involved to be practical.
