AlGaN-based UV-C laser diodes (LD) are expected to be applied to various applications as a low-cost, environmentally friendly, and highly efficient laser light source. Our group has realized the world's first room-temperature continuous lasing of deep-UV LDs by optimizing crystal quality and structure, examining conductivity control methods, and suppressing process-induced dislocations.
