Radio frequency analyser and a method for determining an optimum resonant frequency of operation for laser resonators

摘要

Embodiments discloses a radio frequency analyser (RFA) comprising an amplifier, a dual directional coupler (DDC) unit, a system interface module, a power meter module and a computing unit. The amplifier amplifies radio frequency signals being received from a signal generator. The DDC unit generates forward and reverse RF signals of the load and excite the load circuit using excitation signals through one or more electrodes. The system interface module determines radio frequency power value for each of forward signals and reverse signals generated by the DDC unit. The power meter module obtains laser power value generated on load circuit for each of the excitation signals. The computing unit identifies peak value of RF forward power value and the laser power value of the resonator in synchronisation with the RF excitation frequency and thereby determining optimum frequency of operation for radio frequency excited laser resonators.
