are theses reports of successive tests reliable ?

I would think that by the time these types of reports are released, bad guys world wide have operational systems pointd at their heads

another question: are these systems viable against a reeeally reeeaaalllyyy, mirror-like skinned missle?

Making the missiles shiny will not protect them from this laser.

If the military is willing to release info about a project, odds are they have already tackled the next step. There is no need to keep it secret anymore because there's even better stuff waiting in the wings. This is targeted specifically at those bad guys.

...are these systems viable against a reeeally reeeaaalllyyy, mirror-like skinned missle?

Any mirrors would have to be optically perfect to deflect the beam. Any imperfections (dirt, fingerprints, abrasions from travelling through the atmosphere...) would absorb energy.
