The gapless, linear energy spectrum of graphene can lead to population inversion and negative dynamic conductivity in the terahertz range when graphene is optically or electrically pumped, which makes it possible to create a new type of graphene terahertz lasers. This paper reviews recent advances in scientific challenges to create graphene-based terahertz lasers.
