An immense progress in studying topology, initiated by topological insulators, has extended from its original domain of condensed matter to many other areas of physics such as acoustics and especially photonics. The general feature of a topological state is robustness against defects which makes it experimentally appealing to address numerous issues in nanophotonic both basic and applied. Recently, the active materials were used to implement topological states in  photonics. The effort has led to the demonstration of new sources of coherent light guided by the principles of continuous deformations and topological invariants. Topology gives access to a new paradigm in engineering light with unprecedented properties. This session will discuss the basic principle of topological optics especially used to demonstrate new type of lasers and the session will discuss prospects in addressing long standing questions in lasers physics.
