Abstract

The coupling technique of high-power semiconductor laser array is an advancing key project. A high power density collimated beam, which facula is much smaller, can be get by coupling high-power laser array with selfoc lens array. At the same time, the coupling efficiency is higher. The factors which affect the coupling efficiency mainly include NA, diameter, length and end surface fabricating of selfoc lens and coupling technique. In this paper, an 1×19 linear laser array which maximum continuous output power is 22W is coupled with a corresponding selfoc lens array. The maximum coupling efficiency is 58.2%.
