Claim Text:
1. A laser device including a laser resonator, the laser resonator comprising: a first mode shaping including multiple resonator mirrors which have a telescopic geometry including a combination of at least one convex resonator mirror and at least one concave resonator mirror, a concave-convex geometry or a superposition thereof, and which has a thin disk laser medium providing one of the multiple resonator mirrors, said first mode shaping section is for adjusting a beam diameter of a circulating electric field in the thin disk laser medium, and a second mode shaping section which includes a Kerr medium, the second mode shaping section is for adjusting the beam diameter of the circulating electric field in the Kerr medium, wherein the first and second mode shaping sections are for adjusting the beam diameters of the circulating electric field in the thin disk laser medium and in the Kerr medium independently of each other.
