Abstract

Single-frequency operation or locking in a lateral array of three laser oscillators is studied within the composite-cavity-mode approach. We compute the regions of stable locking, which have a nontrivial shape in the plane of coupling strength versus frequency detuning. The locking regions depend drastically on the amount of amplitude-phase coupling of the lasing field that is quantified by the α parameter. For small α, locking is possible for arbitrary coupling, but only if the middle laser has sufficient frequency detuning from the two outer lasers. In contrast, for larger α, locking is only possible for weak to moderate coupling, provided that all three lasers have similar frequencies.
