• Coupling coefficient
• Diode laser array
• External cavity
• Phase locking

Expressions describing couplings between different emitters of a diode laser array (DLA), positioned in an external cavity (EC), have been deduced. The results show that: the increase of the EC length reduce the differences between these coupling coefficients, which is favorable to achieve the parallel coupling at the expense of the effectiveness of the EC; decreasing the reflection coefficient at the front facet of the DLA is favorable to achieve phase locking in EC; the more parallelly coupled the emitters arc, the lower the allowed reflection coefficient at the front facet of the DLA is.
