Abstract:
A laser amplification system comprising:several solid-state volumes having a laser-active medium, a pumping radiation source for generating a pumping radiation field for the optical pumping of the laser-active medium, a pumping radiation reflector associated with each solid-state volume, said reflector allowing an incoming leg of the pumping radiation field entering the solid-state volume to pass through the solid-state volume again as an outgoing leg, the incoming leg and the outgoing leg forming an angle with one another located in a first plane and forming a first pumping branch for each solid state volume, a first pumping radiation path through the solid-state volumes, the first pumping branches of the solid-state volumes being arranged in said path so as to follow one another such that the pumping radiation field passes through the several solid-state volumes in a first sequence, wherein: each solid-state volume is penetrated by a second pumping branch, the incoming leg and the outgoing leg of said second pumping branch being located and forming an angle in a second plane different from the first plane, a second pumping radiation path is provided, and the second pumping branches of the several solid-state volumes are arranged in said second pumping radiation path so as to follow one another such that the pumping radiation field passes through the solid-state volumes in a second sequence.
