Efficient 1.94-µm Tm3 + laser in YVO4 host
Abstract
A room-temperature Tm:YVO4 laser at 1.94 microns has been demonstrated for the first time. This laser is characterized by a broad bandwidth and a large absorption cross section for the 800-nm pump band. A slope efficiency of 25 percent was obtained under nonoptimal conditions.
