Abstract

An aspect of the invention relates to a method for amplifying a laser beam in a laser amplifier system (10) including a laser amplifier module (12) and an optical module (14), the method comprising:- generating an excited volume in a laser amplifier module (12) so that a surface (19) of the laser amplifier module (12) facing the optical module (14) includes an excited area (20);- coupling the laser beam (24) into the laser amplifier system (10);- conducting a first amplifying pass by reflecting the laser beam (24) multiple times between the optical module (14) and the laser amplifier module (12), wherein each time the laser beam (24) is reflected from the optical module (14) to the laser amplifier module (14), the laser beam (14) impacts on a respective impact area (I2-I47) of the surface (19) of the laser amplifier module (12),wherein the size of each impact area (I2-I47) is smaller than the size of the excited area (20), andwherein a subset of impact areas of all of the impact areas is located on distinct positions of the excited area (20).
