Abstract: A beam diffusing module including a light incident terminal, a light emitting terminal, a first reflective plate and a second reflective plate is provided. The first reflective plate and the second reflective plate are disposed on a transmission path of a laser beam. At least one of the first reflective plate and the second reflective plate has a plurality of reflective micorstructures. The reflective micorstructures are arranged along a second direction from the light incident terminal towards the light emitting terminal. At least a part of the laser beam enters the beam diffusing module through the light incident terminal and emerges from the light emitting terminals after being reflected repeatedly by the first reflective plate and the second reflective plate to cause an M squared of the laser beam to be redistributed along a first direction. A beam generating system is also provided.

Abstract: A beam generating apparatus includes a laser light source, a speckle suppressing module, a light homogenizing module and a driving unit. The laser light source outputs a laser beam. The speckle suppressing module includes two biconic lenses and a diffuser. The first biconic lens is disposed on a transmission path of the laser beam. The diffuser is located on the transmission path of the laser beam between the first and second biconic lenses. The light homogenizing module is disposed on the transmission path of the laser beam from the second biconic lens. The driving unit drives the diffuser to move with respect to the laser beam so that the ratio of the M2 of the laser beam exiting from the second biconic lens in a first direction to the M2 thereof in a second direction is greater than 2, wherein the two directions are substantially perpendicular to each other.
