内容記述 |
Although the pulsed operation of AlGaN-based laser diodes at UV-C wavelengths has been confirmed in previous studies, continuous oscillation without cooling is difficult because of the high operating voltage. In this study, the temperature dependence of key parameters was investigated and their impact on achieving continuous-wave lasing was discussed. A reduction in threshold voltage was achieved by tapering the sides of the laser diode mesa and reducing the lateral distance between the n- and p-electrodes. As a result, continuous-wave lasing at room temperature was demonstrated for the first time at a threshold current density of 4:2kA/cm2 and a threshold voltage of 8:7V. |
