i know about DIRCM, but isn't it just a infrared flasher that overdrives incoming missile's IR sensor and reduces chances of strike on aircraft?
I meant a laser gun of suitable capacity on a moving targetting pod-like thing that can heat up an incoming missile and roast it to kaboom before it reaches near, all kinds of missiles be it infrared sensing or radar ones
For a laser like that, power is not enough in current fighter jets.
Future 6th gen having very high electrical power are "talked about" having a laser for point defense against radar guided missiles, but the laser in this case is considered to be used to mess with the electronics(seeker) of the missile in its nose.
Or a small microwave emitter to mess with the electronics of the incoming bvr missile.
A laser powerful enough that can burn through the missile in seconds at a distance of more few kms is envisioned to be used on "Naval ships" only for now.
The problem here is power, missiles are fast (a missile at the speed of Mach 2 covers distance of 2+km in 3 seconds), a
So you need a laser that is powerful enough to burn through the missile in ideally 1-2 seconds at a distance of more than 3+km, that level powersupply is only possible in ground and ship based systems.
Even then for targets at mach2 or more and hypersonic, currently traditional gun based ciws are much better option "compared to" even a 1MW laser.
Laser are good to deal with relatively slower targets, and powerful lasers good against drones/munitions that try to overwhelm with number.
So for a laser point defense weapon for future fighter 6th gen jets messing with the seeker and electronics is faster and just a better way plus requires way less power.
Lasers are also affected significantly by environment and weather.
US planned to use lasers by putting it on boeing 747 against incoming ballistic missiles, in short the power was not enough, after a dozen kms the laser's energy was too much spread out in the atmosphere to be effective.
So the plan was cancelled.
Then there's Russian peresvet laser weapon (fixed position due to consuming lots of power) that is claimed to be capable of "blinding" the sensors of "satellites" in space.
But depends on good environmental conditions for that.
So while laser weapons are becoming reality.
But a laser on flying plane powerful enough to burn and destroy the incoming missiles under 2 seconds flying at mach2 or similar speeds at a distance of 3+km is "fantasy" for now.
Messing with sensors is a better approach.
But for very slow moving targets like the ones shown in drdo 30kw laser demonstration, destroying by burning them is feasible and preferred due to having enough time to burn them(5+seconds) and having that time at much closer distance( few hundred meters to a km at most).
Another thing is as for "messing" with sensors of the incoming bvr missiles
Much more resilient electronics to deal with it are possible by "current" technology. Though will increase the weight and cost.
So laser while a good addition are not bringing "revolution" in case air defense against incoming missiles atleast for now.
They are good against slow moving targets, but a gun based ciws is good too( somewhat better than lasers), but lasers have two advantages over gun based ciws, 1 massive reduction in cost per shot.
2, not limited by number of bullets stored.
So we haven't reach the technological level to make envisioned role of lasers in future a reality, yet.
Instead alternative ways( messing with sensors, and emergence of slow moving cheap drones) to use them are now being explored.
