    • A beam switch apparatus (100), for deflecting a laser beam (1) from an input beam path (2) along a deflection beam path (3) to an output beam path (4), comprises a rotating mirror device (10) having at least one rotating mirror (11) which can be rotated in a range of rotational angles, wherein the rotating mirror device defines an input mirror surface (12) and an output mirror surface (14) of the beam switch apparatus, and a stationary mirror device (20) having at least one stationary mirror (21), wherein the deflection beam path (3) is spanned from the input mirror surface (12) of the rotating mirror device (10) via the at least one stationary mirror (21) to the output mirror surface (14) of the rotating mirror device (10), and the deflection beam path (3) has a variable spatial course determined by the current rotational angle of the at least one rotating mirror, wherein the at least one rotating mirror (11) and the at least one stationary mirror (21) are configured such that the input mirror surface (12) is imaged in at least one plane onto the output mirror surface (14), and wherein at least one coupling element (31) is arranged in the deflection beam path (3) for coupling at least one temporal laser beam section (5) into and/or from the deflection beam path (3) per rotation of the at least one rotating mirror (11). Furthermore, a regenerative amplifier device and an enhancement cavity device, including the beam switch apparatus, and a beam switching method are described.
