This paper provides an overview of the status of the laser diagnostics to be implemented on ITER. This includes descriptions of the Thomson scattering in the Core, Edge and Divertor regions, polarimetry and interferometry diagnostics used for measuring plasma density and also measurements of Helium density in the divertor using Laser Induced Flourescence. Techniques which can allow improvements on current measurements are also addressed in particular expanding poloidal polarimetry measurements to measure field fluctuations and proposed use of dispersion interferometery which has a number of advantages over existing methods. This paper identifies particular areas where further research and testing on existing Tokamaks is useful even at this advanced stage to inform the design of diagnostics for ITER. Outstanding areas of concern for the implementation of laser diagnostics, in particular with a view to reliable operation are identified.
