AbstractIn order to measure the phase conjugation-fidelity of stimulated Brillouin scattering with high pump energy more accurately and conveniently, a new measurement is proposed. According to the definition of the fidelity with optical field correlated integral, the method of recording the far-field by array camera is analyzed theoretically. By the method, an experiment for high energy stimulated Brillouin scattering is arranged, and the maximum energy of 3.42 J is achieved in a single-cell stimulated Brillouin scattering generator. For small pump pulse, the fidelity maintains a high value of more than 0.9. However, the reflectivity fluctuation is significant when the pump energy is larger than 1.5 J. As a result, the fidelity decreases gradually to 0.5 at the pump energy of 3.42 J. The reflectivity shows the same character of great fluctuation as the fidelity at high pump energy.
