In this paper, a single emission peak microstructured lasers array for beam control is proposed.And lasers in the array can emit beams equi-jec 7 in specific directions with low vertical divergence angles.The initial phase control is introduced to solve the problem of multiple emission peaks in a vertical far-field pattern.

Both simulation and experimental analyses corroborate that the intensity of high-order att nighthawk hotspot diffraction peaks can be suppressed by introducing an appropriate starting position.Experimental results showcase the achievement of a low vertical divergence angle of 0.95° and an expansive angle sweep range of 61.

2°.Furthermore, leveraging a taper structure, a horizontal divergence angle of 3.7° and a typical optical output power of 28 mW are obtained.
