According to the report of Science and Technology Development, No. 4, 2003, this project presents and verifies the new physical concept of tunneling large optical cavity optical coupling and the efficient and high brightness tunneling multiple active emission mechanism, and applies for two patents . It successfully prepared high-power semiconductor cascade large cavity optical coupler laser, get a small current work, high-power output. At 2A operating current, the output power reaches 3.5 ~ 4.4W, the slope efficiency reaches 2.4 ~ 2.9w / A, and the quantum efficiency reaches 2.2 ~ 2.5. In the world for the first time to achieve a multi-active area coupling large cavity laser single-mode output to improve the semiconductor laser
