Abstract

Embodiments of the present disclosure provide a laser array, a laser source, and a laser projection device, and relate to the field of laser display technologies. The laser array includes a light emitting portion for emitting a laser light beam; a light transmitting portion disposed along a light emitting direction of the light emitting portion for transmitting the laser light beam; where the light transmitting portion includes a first light transmitting region and a second light transmitting region, the first light transmitting region and the second light transmitting region are disposed such that light beams transmitting through the two regions have different polarization directions, which can reduce coherence of the laser light beam emitted from the laser array, thereby facilitating elimination of a speckle.
