The Russians have laser dazzlers designed to degrade/"jam" electro-optical imaging satellites. These are currently mounted to trucks and at least one airborne testbed. They are significantly more powerful than laser pointers and they have a prayer of accurately pointing the beam to hit the targeted satellites.

That said, they are dazzlers and not destroyers — they're designed to prevent American recce satellites from cuing American strategic bombers to the location of mobile missile launchers, so just dazzling the satellite's primary sensor accomplishes their task. Of course, that won't work against space-based SAR, but they have RF jammers (and decoys) for that.
