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.
Checking here https://en.wikipedia.org/wiki/Apparent_magnitude the sun is listed as “about 400,000 times as bright as mean full Moon” so pretty accurate.
How much brighter is it than a nice full moon?
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?
