Someone can probably explain this, but it seems odd that they took 192 beams to produce "about 100 times what any other laser regularly produces today." The semantic error aside, excluding the other most powerful lasers, how do you put together 192 beams and only get 100 times the power of an individual beam? Discuss...

192 laser beams to make one monolithic laser. They're saying that the monolithic laser is 100 times more powerful than any other monolithic laser out there.
There are two concepts "laser" here. They have 192 lasers and manage to combine their beams so that the resulting beam still is coherent. Because of that, they call the combined device "a laser", too.

I guess that "any other laser" similarly may be made of a bunch of other lasers. So, tha factor 100 is more "a hundred times as much power as any other coherent beam ever produced"

Mostly, "about 100 times what any other laser regularly produces today" doesn't make any sense unless you include a timespan reference (since energy accumulates over time). Unless I'm being thick and "today" is a timespan reference (i.e. "24 hours") rather than a preposition (i.e. "currently").
