    mig-31bm can't assure that the laser will point at the same area. Remember Ballistic missile can spin as means to resist Laser, letting the area being exposed cool down. Same as Aircraft, and aircraft can do it more freely without fearing of being miss. And no, unless the cockpit is exposed, you wont instantly blind pilot. Thus why you want the engagement time as short as possible. Aside from multiple target engagement. Once laser weapon become common i would expect LWR to be more common to warn pilot that he's being exposed.

    Maybe we can take this study to estimate how many aircrafts needed to saturate the laser based on its engagement time.

    https://www.scribd.com/document/3902...issile-Defense

    We assume the aircraft need to cover 100 Km of range for launch point. mach 0.9. 1 min engagement time. The laser will be saturated by 5 aircrafts. If we have faster aircraft like Mach 1.3, 4 aircrafts will saturate the laser. and so on. If longer ranging missile can be deployed, there could be no aircraft downed and the laser will need to deal with missiles. 1 F-35 can carry or expected to carry Meteor with some 160 km range and may carry as many as 4. and meteor might sustain up to M-3. surviving aircraft can deploy 4 missiles, the laser may have to deal with it and given that M3 missile will cover 150 Km range in just 2 minutes. The laser will be saturated by just 2 missiles, the third might get through.


    garryA I'm already put the spreadsheet. start pulling the numbers. and you seem to have good source too.

      10J/cm2 needed to damage optical sensor
      1J/cm2 needed to damage pilot's eye
      I took 100kW for F-35 HEL with a mirror diameter of 20 cm.
      It can blind IR sensor from 70km in 10 seconds

      By contrast, YAL-1 need about 0.5 second to blind human eye from 1000 km

        Nice

        and yes. that's why we have laser safety.

        I wish i could improve on providing some form of atmospheric consideration. as the original book Dave Hafemeister's Physics of Societal Issues does not go in depth for it.
        and thanks for the book. Now we can expand our target hardness data.

          A naked human eye, but don't pilot visors have inbuilt protection? And I should also point out that using lasers for such purposes would be a breach of the Geneva Convention.

            It might be accidental instead of deliberate.

            British however were having a concept for protecting the pilot tho. In their P-125 concept.

              Some interesting information on phased array lasers in this extract about Zenith Star, which was an SDI-related laser project.

                Some information about adaptive optics here too.
