| Research Abstract |
A high intensity monochromatic gamma-ray source from the laser Compton scattering (LCS) is a very useful probe for a nondestructive assay system by means of nuclear resonance fluorescence. The accuracy improvement of the measurement system is attained by further developing a pure monochromatic LCS source. Since, the monochromaticity of the LCS light source is restricted by the energy spread of the mode-locked short pulse laser, an ultra-narrow band width laser should be used for instead of the short pulse laser. An enhancement cavity for the pure monochromatic LCS source has been developed in this study. An asymmetric confocal Fabry-Perot optical resonator was proposed as an enhancement cavity of the pure monochromatic LCS source. In the result of the study, it was shown clearly that the mirrors of the asymmetric optical resonator should be parabolic mirrors. The influences due to the distortion and the misalignment of the mirrors were evaluated by a raytrace method.
