“Maybe 50 to 150kw.”
Come back when you know the difference between power and energy.
I see that but this is a prototype that isn’t intended to shoot down hundreds of drones in a single mission, rather to demonstrate the technology with a small number of interceptions. I would guess the production system will end up being chemical.
“Must be a chemical laser.”
Liquid lasers obsolete for weapons. Solid state here.
100 kw @ 120v is 833 amps. 100 amp breaker in most small/mid sized homes. Think the energy for about 10 or 12 homes with everything turned on since there is a buffer there in amperage between rated and what actually goes through.
It is quite a bit.
” I would guess the production system will end up being chemical.”
Solid state only.
Operating costs of the aircraft, of course. Plus a Cessna cannot hope to generate the power the laser requires.

You might want to read up on diode pumping.
“Plus a Cessna cannot hope to generate the power the laser requires.”
Please elaborate ...
Probably from energy usage and laser life.
Here is an article about semiconductor and laser marking machines:

Electronics was always my worst subject, but I guess the higher powered the laser the lower its lifespan.
If anyone knows more feel free to chime in.
I would guess that part of the cost involves how many shots components can endure before needing replacement.
energy is what makes change happen, and power is a rate of energy transfer, and yes, conversationally we often confuse/interchange the two, though we shouldn’t, and though most readers either know the difference or are ignorant of the difference, and either way understand the general question anyway
maybe you were confused about the general question
“They think they can outlast Israel’s leftist populace, just as the N. Vietnamese outlasted the USA’s Democrats in the 1970’s.”
So obsolete they're in development now.

“maybe you were confused about the general question”
Nope. The subject post is ENERGY!
“Most lasers need a lot of energy to produce a deadly beam.”
OK, How much?
Your post was kilowatts. Hence my response.
If we assume that a 1 second pulse from a 100kw laser is enough to shoot down a target, then that pulse would be 100/3600 = 0.03 kWh. Multiply by 2 to 4 to account for less than perfect efficiency converting electricity to light.
A very large supercapacitor could hold enough for one shot. Then you need to recharge.
The key here would be how efficient they made the laser.
How many of these are mounted on satellites?
In 2015, General Atomics, with funding from DARPA, produced a prototype ‘High Energy Liquid Laser Area Defense system’ (HELLADS). The liquid laser is actually a solid-state device, but with channels built into the solid material to allow cooling liquid to circulate.
Another from your link (I bet you posted without reading):
In recent years almost all the military focus has been on electrically-powered solid-state fiber lasers.
