An index-guided zinc oxide random laser array was designed and fabricated to achieve spatial overlapping of random spectral modes between the adjacent random cavities. Hence, the number of lasing spectral modes of the laser array can be limited by the phenomenon of spectral repulsion. In addition, the total spectrally coherent emission power can be enhanced by increasing the number of random cavities.
