Correction: I mispoke/mistyped, my laser is a generic, non-MOPA Chinese fiber laser which means it's likely an Q-switched ytterbium fiber laser (I think). _Not_ an "Nd:YAG fiber laser". Cheers to the folks who pointed that out :)

Awesome experiment and vid!. I would suggest that one of the main possible actions of this unique laser machining process is actually achieved by cavitation bubble micro re-entrant jets. Especially when the plasma induced bubble collapses next to the underside of the glass slides surface. So technically you could just use non conductive silicon oil instead of the copper sulphate solution for potentially a much faster etching process. For a more convenient top down machining process the end of your laser head needs to be just below the surface of the silicone oil to prevent unwanted surface laser diffraction. Cavitation micro jets can machine virtually any hard material extremely precisely and deeply even upto diamond hardness, providing your laser is at just the right focal point. Hope that helps and certainly worth experimenting with :)

Hmm, maybe! A few other folks have suggested that too, might give it a shot. Would be pretty easy to tests. I saw some mention in papers of the opposite too... heating everything up so that there was less temperature difference between the glass and the plasma. But cooling seems easier to do so might try that first!

Very interesting. It looks to me as the cavitation erosion does most of the machining in your case. I would expect the surface after etching to be more "round-ish". Also, keep up sharing your unsuccessful experiments, they are as important for learning as the successful ones. All experiments presented in scientific papers are only about the successful ones, but very few people know, that it might be only one out of the hundred attempts (well usually 3 is the needed minimum).

Something tells me that the small bubbles are acting as a collimating "lens" which -- if aligned a certain way with the incoming laser beam -- causes an energetic reaction further below the surface. Likewise, you can see the beam refracting/glanncing off bubbles at the bottom of the test chamber.

I'd bet that this process is just thermal dissolution of silica. To test that, you would expect much faster dissolution/etching rates in more alkaline solutions (higher NaOH). Instead of this purported copper absorption mechanism, you'd only need to suspend a tiny amount of lampblack in the liquid to create intense local absorption/heating.

@BreakingTaps I know this is 2 years old and you probably have researched your way through the wormhole but your walk through of the chemical mechanics behind this started tingling my "Master's thesis research into chemical kinematics of combustion and how their thermodynamics, physics, and micro phenomena in extreme environments extrapolate out into useful energy that we use for propulsion" spidey sense... I think that your assessment at the interfacial layer is fundmentally sound. After viewing the slow motions and observing the significance of the local density gradients that present themselves post-interface, I believe there is a lot of validity to delve further into the free range radicals that you briefly reference, on paper, but assume recombine into water during the voice over. Specifically, that OH radical is -the- chemical signature that becomes an "If-and-only-if" an OH is present does the transition to a plasma state happen. Essentially, unless you see an OH, you don't have a flame, plasma, deflagration, detonation, or henceforth combustion. This is becomes a particularly important definition for systems with operating conditions that are subject to 250 bar AND 4500K+ for time scales of 10+ minutes at a time. Also meeting requirements that they must have the adequate margins to operate for total cumulative lifecycle times in as much as 100+ hours, without service. The analytical research has shown in the past, really 30-40 years since compute resources have been able to run the 120k chemical reactions that occur between nearly 100 chemical species that occur in 2 billitions of a second for a single molecule hydrocarbon, that a large portion of that lifecycle is determine by the near-surface free radical chemistry as opposed to the major combustion products. There is a lot that is going on between the Cu- that is being deposited hyper-localized near-surface and the ionized radical that prepare the surface to "accept" the effects of the cavition without propagating throughout the fairly uniform microcrystalline structure. Definitely more than just the phospho-silanes. This can be observed in the very first high-speed captures you presented of the cavitional nucleation site that essentially "missed" just below the near surface region identified. It is immediately followed by the the effective, and arguably most well represented nucleation site a few microns behind it. If you take note of the density gradients in the solution, I believe that first "miss" helped the drive the success of the secondary pulse. When you compare this to some of the multi-site events captured, there is a correlation between the "missed" nucleation site that generate near surface radicals, be it scavenging or oxidative effects, just ahead of a successful pulse when compared to ones too far behind or below for their sphere of influence to reach the target site before the next pulse arrives. I could go into more detail but I just thought it was worth noting. I applaud every piece of content you present. There is a never a time where you don't have so much more than just the topic of your own interest in any of your videos. You are a golden standard of how science should be conducted and communicated. Thank you.

Pretty awesome. Especially the detailed views and explanation. Some optimization Ideas (not sure if its useful to you): If you degas the liquid before the process (vacuum or ultrasonication), you might get less bubble formation. The latter may have some impact on production quality. Also, sterile filtration with a syringe filter might reduce light scattering in the liquid through tiny particles, homogenizing the bursts. Maybe even with a continuous flow, constantly carrying away the debris.

This was amazing! If you don't need to micromachine-scale features, you can quite easily laser etch glass on the front side by using IR (1013nm) light. Glass is opaque at this wavelength, so the laser energy is absorbed and heats the glass enough that it shatters in place. If you're careful with the power levels you can get quite pleasing results.

I didn't continue this method because it wasn't cost effective for what i was doing but would be awesome for artwork.

Very nice video! I didn't expect to find this topic in such good quality in YT. I would add that there are interesting findings in case of laser micro-machining of materials immersed in liquid. So laser beam is going though air-water interface and then hits the sample. Aspecially promising results are achieved for machining sillicion. This is basically the same setup as nanoparticles sythensis but you are more interested in machined sample topography rather then particles removed from it and there is more focus on water delivery system to improve surface quality (flow/liquid layer thickness). Btw. 1 Are you working in some University where you doing related works? Btw 2. Can you give some more detailes on camera setup that you used?

I've done a little work since this video on both those things! Laser nanoparticle ablation/synthesis (kzbin.info/www/bejne/o5C2lIKLg6aXoq8) and some silicon micromachining, albeit dry instead of immersed in liquid (kzbin.info/www/bejne/iqO8maxuhdGfY5I).

Is there any chance any of the damage to the glass is caused by the bubbles collapsing inward? Reminds me of cavitation bubbles creating pitting on propellers and high speed pumps.
@BreakingTaps
@BreakingTaps 3 жыл бұрын
Definitely possible, although hard to know how much it is contributing. There's a dry variant that uses a plate of graphite (or just metal) directly under the glass. The academic literature claims it's mostly the same mechanism (laser vaporizes graphite and causes a plasma plume), and from my testing it seems faster and more reliable. So I don't think the bubbles can fully explain the machining since it works "dry" as well. That said, I saw a lot of unexplained things in the high speed video, and anecdotally the "machining" rate seems to speed up with increased bubble formation (either due to larger pulses, or tuning the frequency so that you get a constant stream of small bubbles). My uneducated guess is that bubble implosion is contributing to some degree. Maybe extra mechanical shock from the implosion + helping to clear debris, etc? Dunno! Interesting to think about though :)

With the vertical channels of vapor (I think is how you described it, timestamp 12 minutes-ish) you may be observing accumulated self focusing or similar.

Oh, interesting! I hadn't heard of that before, doing some reading now. That does seem more plausible tbh, I was always unsure how to reconcile a "vapor channel" that clearly wasn't a bubble. But a change in refractive index (self-focusing or just from heating) would make more sense imo. Cheers for the tip!
