Abstract
The present invention belongs to the field of laser technology, particularly relates to a semiconductor laser, including a substrate, and lasers, fast axis collimation components, slow axis collimation components, steering compression optical systems, a polarization beam combination prism, a focusing lens and an optical fiber provided on the substrate, wherein the lasers can be arranged in two rows or one row. And lasers of the same row are all located in a same plane. Each laser is sequentially provided with a fast axis collimation component and a slow axis collimation component in the direction of an optical path. The lasers of the same row correspond to a group of steering compression optical systems used to steer and compress the light beams collimated by the fast axis collimation components and the slow axis collimation components. The polarization beam combination prism is used for combining two beams of lasers having been steered and compressed by two groups of the steering compression optical systems. And the laser combined by the polarization beam combination prism is coupled into the optical fiber by the focusing lens. The present invention has a compact structure and a s…
