description The invention provides a laser with high coupling efficiency, which comprises an optical waveguide chip, a fast axis compression lens, a focusing lens and an optical fiber, and is characterized in that the fast axis compression lens is provided with a convex compression curved surface, the generatrix of the compression curved surface is parallel to the slow axis of the optical waveguide chip, and the focusing lens is provided with a convex focusing curved surface; the emergent end of the optical waveguide chip, the compression curved surface, the focusing curved surface and the incident end of the optical fiber are sequentially arranged in the direction of an optical path. The slow-axis divergence angle is equal to the fast-axis divergence angle through the compression curved surface, then the first adjustment light enters the focusing lens with the circular section and is efficiently coupled into the incident end of the optical fiber after being gathered by the focusing lens, fewer devices are adopted, the s
