Problems solved by technology

But as the number of semiconductor lasers increases, the beam quality will decrease
In addition, the particularity of the semiconductor laser structure determines that the beam quality of the fast axis and the slow axis are inconsistent: the beam quality of the fast axis is close to the diffraction limit, while the beam quality of the slow axis is relatively poor, which makes semiconductor lasers suffer a lot in industrial applications. limits
