Sumario:A beam emittance monitor for H- beams based on laserinduced ions neutralization is being developed at the Front End Test Stand (FETS) at the Rutherford Appleton Laboratory (RAL). In this paper we present a full account of the laser system that will be used for the photodetachment experiment, the optical transport system and the final delivery assembly. All the relevant measurements such as power, spatial and temporal characteristics of the laser, fiber coupling efficiency and final delivery laser beam parameters will be reported.
