In order to improve a solid-state laser, in particular a solid-state disc laser, comprising a resonator (40) that defines a resonator radiation field (30) and at least one solid-state disc (12) with the resonator radiation field (30) passing through it, in such a manner that the thermal lens effect can be at least substantially compensated, it is proposed that in reflection the resonator radiation field (30) strikes at least one first adaptive mirror unit (50, 70), with which a distortion of the resonator radiation field (30) as a result of a thermal lens effect of the at least one solid-state disc (12) can be substantially compensated. An adaptive mirror unit (50) can be configured by a heated (58a, 58b) glass sheet (54) with an HR layer (52), for example, or by a pressure-induced deformation by means a fluid (78) in a space (76), which is enclosed with the mirror (72, 74). |
