Topological insulators, such as Bi2Se3 have single Dirac cones on the surfaces and narrow band gaps in the bulk. Their optical absorption becomes saturated under strong excitation. Taking advantage of the saturable absorption and narrow band gap, the topological insulator can modulate the operation of a bulk solid‐state laser as a pulse modulator. (Picture: H.
