Meta-mirrors may help realize ultra-stable lasers for high-precision metrology, for applications like gravitational wave detection and quantum optics. The authors experimentally realize a new type of microstructured meta-mirror and use it to form a Fabry-Perot cavity with low thermal noise and a high finesse of 12,000.
