Abstract

A surface-emitting laser array (10, 10A, 10B, 10C) and a laser device (300) including the surface-emitting laser array (10, 10A, 10B, 10C). The surface-emitting laser array (10, 10A, 10B, 10C) includes a layered product including a lower reflecting mirror (102) having two layers with different refractive indexes, an upper reflecting mirror (106), and an active layer (104) disposed between the lower reflecting mirror (102) and the upper reflecting mirror (106), a first separation trench (11) from which the upper reflecting mirror (106), the active layer (104), and the lower reflecting mirror (102) are removed, the first separation trench (11) separating the surface-emitting laser array (10, 10A, 10B, 10C) from an adjacent chip (10, 10A, 10B, 10C), and a second separation trench (13) disposed between the first separation trench (11) and a light-emitting unit (1) that emits a laser beam, the second separation trench (13) having a prescribed depth.
