This article traces developments in the spectroscopy of high temperature laboratory plasmas used in controlled fusion research from the early 1960s until the present. These three and a half decades have witnessed many orders of magnitude increase in accessible plasma parameters such as density and temperature as well as particle and energy confinement timescales. Driven by the need to interpret the radiation in terms of the local plasma parameters, the thrust of fusion spectroscopy has been to develop our understanding of the following: the atomic structure of highly ionised atoms, usually of impurities in the hydrogen isotope fuel; the atomic collision rates and their incorporation into ionization structure and emissivity models that take into account plasma phenomena like plasma wall interactions, particle transport and radiation patterns; the diagnostic applications of spectroscopy aided by increasingly sophisticated characterisation of the electron fluid. These topics are discussed in relation to toroidal magnetically confined plasmas, particularly the Tokamak which appears to be the most promising approach to controlled fusion to date.
