In summary, the invention relates to an apparatus (10) for illuminating a sample (12) using a plurality of light beams (14b) following one another in synchronized fashion. Acoustic waves generated on the sample (12) by these light beams (14b) are detected by an electroacoustic transducer (20). The synchronous sequence of the light beams (14b) can be achieved by a beam deceleration device (36) comprising at least one beam decelerator (40a-40d), preferably a plurality of beam decelerators (40a-40d). Each beam decelerator (40a-40d) can bring about individual retardations, i.e., retardations that are different from those of the other beam decelerators (40a-40d), of the light beams (14b) passing therethrough. As a result, a large surface area of the sample (12) can be scanned by a rapid succession of light beams (14b) which can be assigned to respective illumination positions. The beam deceleration device (36) can be illuminated by a beam splitter (32). The beam splitter (32) and/or the beam deceleration device (36) can have a planar design. In a preferred embodiment of the invention, starting from the light source (28) to the emergence of the light beams from an optical head of the beam deceleration device (36), the apparatus (10) has predominantly fiber-optic components, and in particular, only fiber-optic components.
