In a more scientific sense, what you’re describing is called an “optical cavity resonator,” and is used in many lasers. The first working lasers used mirrors that were a bit better than 99.9% reflective, and which were positioned so that photons would bounce back and forth between them many times, passing through the “gain medium” (a ruby rod, or mixture of helium and neon gas, in early lasers) on each bounce. It actually does work; the light will bounce back and forth, but not endlessly. In a laser, energy put into the “gain medium” makes up for losses from the mirrors, and a steady-state condition arises with the average photon making several hundred trips through the cavity before escaping through one mirror, which is made in such a way as to allow a small fraction of light to pass through it while absorbing (losing) very little light itself.
