The invention relates to a solid laser resonator which comprises at least two laser active mediums in a common laser radiation field (4), wherein the laser active mediums do not form a hard diaphragm of the common laser radiation field (4). For the solid laser resonator, at least one focusing optical element (17, 18) is arranged between two adjacent laser active mediums in the laser radiation field (4). The focal length and the distance away from the surfaces (9, 10) of the two adjacent laser active medium (2, 3) are chosen to ensure that the surfaces (9, 10) of the laser active mediums (2, 3) are approximately mutual optical conjugate.
