Abstract
A laser amplifier system is provided which comprises a resonator with optical resonator elements which determine a course of a resonator radiation field which propagates along an optical axis and at least one laser-active medium (LM). The resonator is designed as a split resonator and has a first resonator section which extends from a first virtual plane of separation and a second resonator section which extends from a second virtual plane of separation. The resonator sections are dimensioned optically such that the resonator radiation field has radiation field states corresponding to the same resonator modes in each of the virtual planes of separation. An amplifying unit optically independent of the resonator is arranged between the first and the second virtual planes of separation. The amplifying unit comprises the at least one laser-active medium and couples the radiation field states in a neutral manner with respect to the resonator modes.
