ABSTRACT:
A speckle reduction laser and a laser display apparatus having the speckle reduction laser are provided. The speckle reduction laser includes a semiconductor unit that comprises an active layer and emits laser light through a first side surface thereof by resonating light generated from the active layer, and a vibration mirror unit disposed adjacent to a second side surface of the semiconductor unit. The laser further includes a mirror, and the resonance of the laser light is generated between the first side surface of the semiconductor unit and the mirror, and a resonance mode of the laser light is changed according to the vibration of the mirror.
