No you missed your physics classes.
CIncreasing the power and repeating will make no difference whatsoever. If there is no "line of sight" then laser transmission without an optical wave guide (aka a fibre optic cable) is a none starter.
For the purposes of free air laser transmission light only travels in straight lines. That is no gravitational lensing, and no fancy ultra modern optics which basically are of no use in this scenario.
So repeat after me you idiot no line of sight no transmission.
That is true if you live in vacuum...
The athmosphere will scatter the laser light. If you keep increasing power you might detect that light even if you have no direct line of sight... or melt the planet.
