摘要：
This paper's main purpose is collimating, shaping and coupling semi-conductor laser beam by one-dimension gradient-index lens with parabolic-index profiles along the direction of thickness has been fabricated by ion-exchanging process. Introduced the ray matrix equation of One-dimension gradient-index lens and formation process of parabolic-index profiles. Measured distribution constant of refraction root A in varied thickness. Using one-dimension gradient-index lens with varied thickness replacing cylindrical lens collimating, shaping and coupling semi-conductor laser beam. Using two perpendicular one-dimension gradient-index lens shaping laser beam by two direction. Maked a mini and new semiconductor laser coupler. Demonstrated a coupling efficiency of 80% which from semi-conductor laser beam into single-mode fiber.
