Reflecting a laser from earth all the way back to space is hard. The recently launched NASA satellite to look at the extent of polar ice fires a laser at earth and looks at the reflection. Ice is reasonably reflective yet even then the satellite gets about 1 photon back for every 1e12 it sends out.

Firing a large laser is expensive in terms of energy and expensive in terms of temperature: once a satellite is hot, it is not very easy to call down. All you can do is try to radiate the heat away but that’s not so easy or effective.
