I reckon something like it will, at some point, but a quick glance at their website doesn't inspire confidence, though

well thank goodness

I assume that this is a "demonstration" photo:

great, they seem to have singed a 5cm branch, though it doesn't look like they cut through it - or even into it.

Perhaps they work better in completely still air, where the branches don't move at all.

I'll believe that these are "coming" when a reputable source shows a demo, even if it's connected to a 100kW generator.

Till then, these are vaporware with just a hint of smoke from that pic ^

Reading further, we do find on Goman's site:

it's basically a balloon string burner.

No, it's not going to cut wood any time soon.

A few years ago laser welding was like that, look where it is today. I said it's coming, may never replace climbing or lifts completely, Also not sure battery saws will be a complete answer. IMHO

IMO drones will supplement the trade first, way easier technical problems to solve, and then political/safety problems, as such a laser is going to be a pretty serious public safety risk and my guess is that your typical tree crew isn't going to be able to afford the training for running a laser like that.

I could really use a drone even with simple loppers or a small saw to cut some mistletoe out of my oak trees - I can't afford to get a tree guy out with a cherry picker on the hill to get them out vs the value of the tree, but I'd be glad to spend like the cost of getting it all out of one tree on a pruning drone, then I can do all of my trees...

You may well be right. Tech dies on the vine all the time. The big problem is energy/heat absorption by wet wood. Much easier if it is dry as we all know from fire wood.

Remember Ronald Reagan's Star Wars initiative 40 years ago? One thing that came out of it was advanced laser technology and flea markets were flooded with internally etched paperweights.
Lasers can be designed for distance, power, etc. and like everything it will become more affordable years to come. We may not live to see it.
