Abstract
A ytterbium-doped silica microcavity laser demonstrates stable laser emission while completely submerged in water. To our knowledge, it is the first solid-state laser whose cavity mode interacts with water. The device generates more than 2 μW of output power. The laser performance is presented, and low-concentration biosensing is discussed as a potential application.
