| Abstract(in English) | A focusing optics consisting of an elliptic mirror and a parabolic mirror is proposed to focus the crescent-shaped blue laser beam radiated from the channel waveguide Cerenkov SHG. One of the merits of this mirror focusing optics is that the direction of the focused beam can be set in accordance with the practical usage. By using the ray tracing method, RMS aberration of this optics was figured to be less than 0.07λ(Marechal's criterion). The calculation based on the ray tracing method and the integral theorem of Kirchhoff for the focused beam reveals that the beam width obtained in the designed mirror optics is very near the desired one with deviation less than 1%. The anisotropic effect of the SHG device was compensated by moving the parabolic mirror along it's symmetric axis. |
