Abstract
In recent years, second-harmonic generation (SHG) using periodically poled nonlinear crystals has attracted considerable attention. We developed a 423-nm light source using an 846-nm tunable diode laser. To evaluate the performance of the light source, we irradiated an SHG light at a calcium atomic beam and the observed fluorescence spectrum. Isotope selective photo-ionization of calcium atoms was performed using the developed light source.
