Optical sensing with dichroic resonator

For more than a century, optical resonators (e.g., Fabry-Pérot, FP) have been used as interferometers, high-resolution spectrum analyzers, and fast displacement sensors in both fundamental research and metrology. The ability to measure a given quantity simultaneously at two orthogonal polarizations led to new applications that are still being investigated. Later research has shown that FP can be easily employed in modern quantum optics (atom-light strength coupling tests) and in high-energy physics experiments (resonant enhancement of the conversion probability). We present a dichroic FP resonator that is simultaneously resonant for two wavelengths: 1064 nm and 532 nm, its properties and possible applications.
