Tuning the wavelength of lasers is basic to many uses of light. This research activity will develop a new mechanism for electronically tuning lasers. The objectives are to make more rapidly tunable lasers that are efficient and reliable. The tuning method is by suppressing unwanted longitudinal cavity modes, or equivalently unwanted wavelengths. The loss mechanism is based on a coupling between a laser cavity's fundamental transverse mode we wish to suppress and a higher- order higher-loss transverse mode of the same laser cavity. The coupling is by an acousto-optic modulator in the cavity. A successful Phase I and Phase II program will produce tunable continuously-emitting and pulsed lasers relevant to a wide range of research and measurement applications.

调谐激光的波长对光的许多用途是基本的。这项研究活动将为电子调谐激光器开发一种新的机制。其目标是制造更快、更高效、更可靠的可调谐激光器。调谐方法是通过抑制不想要的纵腔模式，或等效地抑制不想要的波长。损耗机制是基于我们希望抑制的激光腔的基横模与同一激光腔的高阶高损耗横模之间的耦合。耦合是通过腔内的声光调制器实现的。成功的第一阶段和第二阶段计划将生产与广泛的研究和测量应用相关的可调谐连续发射和脉冲激光。
