Query: An in-situ method for measuring the non-linear response of a Fabry-Perot
  cavity   High finesse Fabry-Perot(FP) cavity is a very important frequency reference
for laser stabiliza- tion, and is widely used for applications such as
precision measurement, laser cooling of ions or molecules. But the non-linear
response of the piezoelectric ceramic transducer (PZT) in the FP cav- ity
limits the performance of the laser stabilization. Measuring and controlling
such non-linearity are important. Here we report an in-situ, optical method to
characterize this non-linearity by measuring the resonance signals of a
dual-frequency laser. The differential measurement makes it insensitive to
laser and cavity drifting, and has a very high sensitivity. It can be applied
for various applications with PZT, especially in an optical lab.
