How far could this really be scaled into?
A death ray able to penetrate an aircraft carrier's hull would be a wet dream for every military fag for sure.
How much energy do such lasers lose if they would be able to penetrate at one side of a hull?

You don't need to penetrate the hull, you just have to fry the pilot's retina. This would be against the Geneva convention but it's not like Americans (among others) would care.

>Project Excalibur was a Lawrence Livermore National Laboratory (LLNL) Cold War–era research program to develop an X-ray laser system as a ballistic missile defense (BMD) for the United States.
>The concept involved packing large numbers of expendable X-ray lasers around a nuclear device, which would orbit in space.
>During an attack, the device would be detonated, with the X-rays released focused by each laser to destroy multiple incoming target missiles.[1]
>Because the system would be deployed above the Earth's atmosphere, the X-rays could reach missiles thousands of kilometers away, providing protection over a wide area.

the main problem with high intensity directed energy weapons like lasers is that you run into a problem called "blooming" where the laser ionizes the air, which scatters the laser light such that it loses focus.

the cool thing about this is that conceptually you could make an ionized channel in air and then send lighting bolts down the channel to fry your target, a la homing plasma from radiant silvergun https://youtu.be/wmbtRW0noRw?t=1632

requiring line of sight is a serious drawback for ship based weapons. It makes sense for a plane and makes more sense for missile defense.

surely chrome doesn't reflect all wavelengths though and the laser almost certainly isn't visible light in the first place.

Taiwan is best girl. If Chyna tries to plunder best girl Taiwan, they are in for a world of hurt.
Chyna should shrink its population by 50% to avoid collapse, and the only way to achieve that while maintaining geopolitical parity is for China to invade India and Russia at the same time.

seriously?

do we at least know what specific doping materials, therefore what specific line-spectrum wavelength they're using?

anything specific?

I'm thinking ahead to when they get serious about this stuff.....

they'd be looking back to now at chuckling at how small their laser-pointers were.

CO2 lasers are easier to machine in your back shed and make yourself.
semiconductor based stuff means you can only get what you can buy.
I am disappointed.

I'm gonna have to stick with my CO2 approach.

There is no medium to erode with a fiber laser and power output is continuous, as long as there is electrical power to drive the laser, which is why the Navy and Air Force are both investing in them.

all semiconductors have a limited lifespan.

many lasers can be CW and keep going happily if properly cooled.
>which is why the Navy and Air Force are both investing in them.
yeh, I guess it does make sense.
they can easily stockpile what the USA manufacturing sector can easily produce themselves.

doesn't help me though, getting lots these in an attempt to combine them is kinda messy and the paper trail will race eyebrows.

I'd be better off tossing the glass-tube idea and machining a CO2 cavity.
Can you make a better suggestion for someone who's both paranoid and supposes his country will be the one of the first China conquers in WW3?

Lmao, Ill just cover the hull with some aluminium wrap and your laser becomes useless
If you make a laser strong enough to burn through it will also ionize the air meaning it will lose a fuckton of energy before it even arrives.
Such weapon may only work in space
