Accurate Determination of Q Factors of a Quasi- Optical Resonator
This paper presents a novel approach to measuring the Q factors of a quasi-optical resonator used in a free electron maser (FEM) operating at 100 GHz. Estimation of the Q factors is based on measuring the reflection coefficient in the vicinity of resonance frequencies. The unknown parameters (attenuation constant and coupling inductance) are determined from the numerical solution of a nonlinear...
متن کاملFrequency conversion in a high Q-factor sapphire whispering gallery mode resonator due to paramagnetic nonlinearity.
Nonlinear frequency conversion is a well known and widely exploited family of effects in optics, often arising from a Kerr nonlinearity in a crystal medium. Here, we report high stability frequency conversion in the microwave regime due to a χ(3) nonlinearity in sapphire introduced by a dilute concentration of paramagnetic spins. First, we produce a high stability comb from two microwave fields...
متن کاملMeasurement of the Q value of an acoustic resonator.
A cylindrical acoustic resonator was externally driven at the first resonance frequency by a compression driver. The acoustic energy stored in the resonator and the power dissipated per unit time were evaluated through the simultaneous measurements of acoustic pressure and velocity, in order to determine the Q value of the resonator. The resulting Q value, being employed as a measure of the dam...
متن کاملAccurate Optical Frequency Measurement and Synthesis
In recent times a remarkable breakthrough has occurred in the field of optical frequency measurement and synthesis. For the first time it is now possible to generate arbitrary waveform light pulses, perform accurate optical frequency synthesis and accurately measure the frequency of optical frequency signals. These long dreamed of possibilities have been delivered because of the existence of tw...
متن کاملHigh-Q Resonator with Integrated Capacitance for Resonance Power Conversion
Resonant power conversion at MHz frequencies is useful for miniaturization of power electronics, but requires resonators or inductors with high efficiency. Because litz wire is not effective above several MHz, an alternative winding structure for inductors is required for operation at these frequencies. In this paper, we present resonators with a multi-layer foil winding which can be constructe...
