Why not? There’s a bunch of applications where that is a requirement.
The Lunar Laser Ranging experiments are a fun one, I think. Scientists shoot lasers at mirrors placed in the moon and measure the trip time of light to calculate the distance of the moon to the millimetre.
However:
Out of a pulse of 3×10E17 photons aimed at the reflector, only about 1–5 are received back on Earth, even under good conditions.
You do know the moon doesn’t generate its own light, right?
Apparent magnitude DGAF
A mirror doesn’t generate its own light either, but would you try shooting a weapons grade laser into one and pointing it at one of your eye sockets?
I wouldn’t compare the brightness of a laser to a reflection of itself. That’s the issue I’m seeing.

Pssh! You still believe in the moon?
