Design of a high average power Nd:YAG laser system and a prototype laser amplifier for the edge Thomson scattering system in ITER was conducted. The target performance is 5 J of output energy and a repetition rate of 100 Hz for the laser system, and 1.6 J of extracted energy for the prototype amplifier. A prototype amplifier was produced, after which the small signal gain and extracted energy reached up to 12.6 and 1.76 J, respectively.
