An introduction of laser weapons is briefly given here,as well as damages of missiles.There are many effective laser countermeasures,for instance,spinning missile,superhigh sonic missile,reinforce structure (materials),including light reflection coatings,heat insulation coatings and photoelectric protection technique.Missiles with laser countermeasures will be capable of surviving.It would be one of the most important researches for us to intensify radiation and quicken up damage in the field of laser weapons.
