- 論文の詳細を見る
A hemi-paraboloidal solid immersion mirror (HP-SIM) was for the first time fabricated with the electrolytic in-process dressing (ELID) grinding technology. By improving the surface deviation and roughness of the HP-SIM to the order of $\pm 0.3$ μm and 4 nm, the spot size (FWHM) of $0.22\times 0.26$ μm was obtained in the blue light concentration with the HP-SIM though fairly large side lobes were observed. A small-sized optical head was also designed with the HP-SIM, a pair of collimating lenses, and laser diode, which height can be reduced to 1 mm. Diffraction limited concentration is expected with the HP-SIM optical head, though the accuracy of less than $\pm 1$ μm is required for the alignment of the LD to the collimating lenses for both $X$ and $Y$ directions.
