Implementation of a doubling cavity to producea 423nm light source for the excitation of Caisotopes

摘要

For selective excitation of isotopes of Ca, a 423nm narrow linewidth, continuous wave (CW)light source which corresponds to the S-P transition (4s~2~1S_0- 4s4p ~1P_1) is required. A solid state CWlight source which generates 423nm is difficult to commercially use. Therefore, we have developed a Second Harmonic Generation (SHG) system to obtain 423nm lights from 846nm lights by using anonlinear optical crystal
