It is known that, for an asymmetric limacon cavity with no mirror symmetry, resonances always appear in pair (chiral pair) with high non-orthogonality and chirality when non-Hermitian boundary condition is imposed. We show that the result of the laser numerical simulation with Maxwell-Bloch model can be represented by the locking of a chiral pair by using semiclassical Lamb laser theory. It was revealed that, at the exceptional point where the chiral pair becomes degenerate, the stationary lasing state is either only clockwise or only counter-clockwise emission.
