Wide Range Controllable Direction Single Emission Peak Microstructured Lasers Array

Blog Article

In this paper, a single emission peak microstructured lasers array for beam control is proposed.And lasers in the array can emit beams in specific directions with low vertical divergence angles.The initial phase control is introduced to solve the problem of multiple emission peaks in ultrastar dc hc550 a vertical far-field pattern.Both simulation and experimental analyses corroborate that the intensity of high-order diffraction peaks can be suppressed by sawgrass virtuoso sg500 complete sublijet sublimation printer kit 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.
