The optical resonator is a set of mirrors in the laser system. One of many skills of a laser is to energize the atoms to get them in an excited state.

Photons replicate off of both of the mirrors and energize other electrons to discharge much more photons. The mirror at one end lets some light by means of, which is the laser beam.
