Semiconductor lasers exhibit unusual behavior against conventional optical elements due to spatial non-homogeneous in both fast and slow directions. In order to modify the behavior of these lasers, their beam parameter product (BPP) must be equal in both fast and slow directions. One of the method of beam shaping is using beam transformation system (BTS). The BTS installation needs the high accuracy tools. In this paper, the BTS element and coupling lens are simulated for coupling laser bar and the angular error was surveyed for optimization of installation process. The experimental results show the 75% coupling efficiency is achievable in improvement system.
