  Inspired by the idea of non-Hermitian spectral engineering and non-Hermitian
skin effect, a novel design for stable emission of coupled laser arrays with
tunable phase locking and strong supermode competition suppression is
suggested. We consider a linear array of coupled resonators with asymmetric
mode coupling displaying the non-Hermitian skin effect and show that, under
suitable tailoring of complex frequencies of the two edge resonators, the laser
array can stably emit in a single extended supermode with tunable phase locking
and with strong suppression of all other skin supermodes. The proposed laser
array design offers strong robustness against both structural imperfections of
the system and dynamical instabilities typical of semiconductor laser arrays.
