A nuclear magnetic resonance probe is provided comprising a high frequency resonator having a resonant frequency, a first coaxial conductor connected to the high frequency resonator, and a high frequency supply which supplies the first coaxial conductor the resonant frequency of the high frequency resonator. The high frequency supply includes a conductive sampling loop at least partly placed in the high frequency resonator and a broad band, high frequency, amplifier having an input connected to the sampling loop by a second coaxial conductor and an output connected to the first coaxial conductor. The assembly forming a high frequency loop oscillator locked to the resonant frequency of the high frequency resonator.
