  Coherent beam combination is one promising way to overcome the power limit of
one single laser. In this paper, we use a Multi-Plane Light Converter to
combine 12 fibers at 1.03 micron with a phase locking setup. The overall loss
measurement gives a combination efficiency in the fundamental Hermite-Gaussian
mode as high as 70%. This setup can generate the fundamental and higher-order
Hermite-Gaussian modes and has beam steering capabilities.
