工作波长为 398 nm、输出面涂有多层抗反射涂层的 InGaN 激光二极管已在利特罗外腔内运行。已实现 6.3 nm 的最大手动调谐范围，以及使用单个压电控制的 0.8 GHz 连续调谐范围。线宽小于11 MHz，实现了稳定的单纵模工作。讨论了利特罗腔内二极管输出面的方向对总调谐范围的影响。
An InGaN laser diode operating at 398 nm and with output facet coated with a multi-layer anti-reflection coating has been operated within Littrow external cavities. A maximum manual tuning range of 6.3 nm has been achieved and a continuous tuning range of 0.8 GHz with a single piezo control. Stable single-longitudinal-mode operation has been obtained with a linewidth less than 11 MHz. The effects on total tuning range due to the orientation of the diode output facet within the Littrow cavity are discussed.
