Abstract

A new method for high-speed determination of the frequency separation between two laser sources is presented. The system is based on an artificial neural-network controller implementing a radial basis function network. The controller processes the signal produced by a scanning Fabry-Perot resonator in order to evaluate the frequency separation with good accuracy and bandwidth. The flexibility and the low cost make this approach suitable for application in spectroscopy and related fields. The system can be applied without substantial modifications to any tunable laser source
