Looks like lucrative US patents on the way, along with better, cheaper TVs, and cool death rays! Thanks Talisker.

Fascinating abbreviation, I just looked it up.

Almost like it was made for me, LOL...

Ok, I have a stupid question for our resident science gurus.

Why haven’t we developed a hand-held Laser weapon?

We have Lasers that easily cut through steel. Is it because of strength dilution at distance, or because there’s no way to stop at one kill, in other words, Laser goes through 6 people instead of one?
Or is it an energy generation issue, still requires more power generation than we can carry?

Energy. Lasers are hooked to the power grid. My guess is that battery lasers would not cut thru steel. Or it could cut thru steel for about 2 seconds then need a recharge.

the problem with the a hand held laser weapon is primarily the thick cord that makes it unwieldy and hard to aim

The perfect weapon to blind enemy troops or pilots.

And that the thick cord is attached to the better part of your local power grid.

Once upon a time when I was a student working in a lab with a fairly powerful laser, I had to do all manner of safety stuff and learned a good bit about the equipment.

One of the more notable things was that it was a single digit watt output laser, which had a kilowatt power source which plugged into the wall.

No doubt there are more efficient set ups than I used oh so many years ago, but the simple truth is that lasers are just not very efficient in terms of energy in vs. energy out. The ones used on the ABL for example are chemical lasers, so they work by causing a chemical reaction which dumps a lot of energy in a short time, which creates the beam.

So as we come across Higher output, quicker charge batteries such as the one being developed by Musk, or the Graphene Battery, we might see an answer to the energy issue.

Would the “steel cutting” Laser maintain its lethality at 50-60 yards, or 100 yards?

Theoretically a laser has infinite range, the question is focus.
