Abstract

Device for modulating a laser beam, comprising a deformable mirror (2) provided with a reflective surface (21) adapted to receive an incident laser beam (101) and to reflect a corresponding reflected laser beam (102) provided with an output wavefront (FU) and actuator means operatively associated with said reflective surface (21) and actuatable for deforming said reflective surface (21). The modulation device (1) also comprises detection means (3) provided with an electromagnetic radiation source (31) adapted to emit a control beam (311) incident on the reflective surface (21), and a wavefront sensor (32) placed to intercept the reflected control beam (312) reflected by the reflective surface (21) in order to detect measurements of the wavefront of the reflected control beam (312) itself and generating corresponding measurement signals (Sm). In addition, the modulation device comprises a logic control unit (4), which receives the measurement signals (Sm), is arranged for associating the latter with corresponding forms of the output wavefront (FU) of the reflected laser beam (102), is operatively connected to the actuator means in order to actuate them to deform the reflective surface (21) in order to feedback control the form of the output wavefront (FU) of the reflected laser beam (102).
