Abstract
A laser amplifier includes a laser-active solid-state rod, through which an input laser beam passes at least twice, and a pump device for generating at least one pump laser beam which is incoupled into the solid-state rod via a first end face of the solid-state rod in order to optically pump the solid-state rod. The input laser beam is incoupled into the solid-state rod via a second end face of the solid-state rod. The input laser beam amplified in the solid-state rod is outcoupled from the solid-state rod in order to form an output laser beam. The laser amplifier further includes a dichroic mirror arranged in a beam path of the pump laser beam between the solid-state rod and the pump device and at an right angle to the pump laser beam. The dichroic mirror is transmissive for the pump laser beam and reflective for the input laser beam.
