If you fire a laser against a mirror, it bounces but raises the heat of the mirror so you end up melting the mirror and destroying the drone.

    Depending on how long you do it, how powerful the laser, and how quickly it can cool off at the same time.

    And like the other guy said, you can make really good mirrors if you only care about one wavelength.

    But the drone stays in the air by making wind, which would cool down the mirror?

    Unironically yes. If that's not enough, add water.

    not if you have total internal reflection

    In all seriousness, wavelength-specific dielectric mirrors can approach six nines of reflectivity.

    The hard part is hitting the mirror instead of the drone.
