Abstract (in Japanese) (See Japanese page) 
(in English) Recently, the group reported the realization of current injection semiconductor lasers in the UV-B region. In the future, reducing the threshold current density will be the most important issue. In this study, we fabricated a GRIN-SCH structure current injection laser that can obtain a high light confinement coefficient Γ and can be expected to have a low threshold current density, and confirmed the operation of a room temperature pulsed laser with oscillation. Wavelength of 302 nm. Furthermore, it was confirmed that the threshold current density was reduced to 24 kA/cm2 by double-side facet coating at a cavity length of 700 µm.
