Does it posible to build small size laser and enough powerfull to destroyed land-air missile?

If yes. then how?

If no. then why?

anything is possible
it all depends on the power source that you would use for the laser and the range that you want


(learn to spell)

It would fit in a short bus and maybe a large work (not soccer mom) van.

Lasers waste lots of power by making heat and light that is not used, so they need big power supplys and or big gass tanks.

What about aircraft witj size of f-18, f-22 or su-47 (fighters)?
And then be air suport for ather fighters. when it go in enemy territory.

Well no.

I think about fighter plain, not boing 747 (flyng castel)

I was thinking about manoeuvreble plain.

Does it posible?

Nope, lasers like those are way too heavy to be in anything that is supose to be agile. These lasers are at least 1000 pounds, fighters need to be as light weight as possible.

The Joint Strike Fighter is getting equpied with a laser.

A laser? For what use, painting targets, range finding? How big is this fighter?

Yeah, thats a low power laser it can probably burn through black paper but not through steel.

I doubt even that.... Most of these lasers in the 1 Watt or less range (total optical power-for comparison the average laser pointer is 1 milliwatt).

To start to burn through anything you would need at least 10 watts (given a 2 cm square beam - typical with long ranges) of continuous power (much less if it is pulsed).

The size of lasers needed to burn through anything substantial is still quite large, far too big for any fighter aircraft.

I have seen 2 watt laser diodes burn black paper on ebay and my stupid friend made a red squiggly mark on the back of his hand with a 100mW multi-line argon laser. 10W is the point where the fun starts lol.

Like I said, it all depends on the beam size. Within short ranges you can get very small beams. But with the ranges you deal with in military applications very large beam sizes are a fact of life.

No matter how good your optics are you can't get around atmospheric distortion.

Well yeah, at a distance the beam does widen and the 10W would be needed at miles away to do that.

What's the power of the lasers that the military is developing to shoot down artillery shells and missiles I saw one of those lasers on TV and the laser beam itself was the width of a finger but it burned a hole through a 1 inch carbon steel plate in about 4 seconds.

The power to do that is over 4KW output, probably 10KW or more input. CO2 lasers are about 30% efficient. If its a chemical laser, it still needs to output 4KW and up to burn through steel that fast.
