Optically pumped solid-state laser

An optically pumped solid-state laser comprising:

• a pump radiation source and
• a laser resonator for forming at least one standing wave with an active laser medium extending in layer-like fashion,
• wherein the pump radiation source and the laser resonator are arranged relative to one another in such a way that the laser resonator can be pumped by the pump radiation source,
• wherein the laser resonator is delimited at a first end by an end mirror for reflecting the standing wave, and at a second end by an outcoupling mirror for reflecting the standing wave and outcoupling laser radiation,
• wherein the laser resonator has at least four reflectors at which the direction of extent of the standing wave changes,
• wherein the end mirror, the outcoupling mirror and the reflectors are arranged relative to the laser medium in such a way that the standing wave extends through the laser medium along its direction of propagation and is then reflected at two successive reflectors at a top side of the laser medium and then once again extends through the laser medium and is then reflected at two successive reflectors at the bottom side of the laser medium and then once again extends through the laser medium.
