Answer
Schawlow used mirrors for creating lasers. He used a Fabry-Perot interferometer with a pair of highly reflecting mirrors to create a standing wave of light in the laser cavity. The mirrors reflected the light back and forth, causing it to build up in intensity until it reached a level where it could lase.
