Zusammenfassung:The present technology provides a surface emitting laser element capable of reducing variation in light emission intensity between light emitting units adjacent to the second region and light emitting units other than the light emitting units.A surface emitting laser element according to the present technology includes: a substrate; an electrode provided on one surface of the substrate; a first region which is provided on a side of the one surface opposite to a side of the electrode and in which a plurality of light emitting units having mesas is arranged; and a second region disposed around the first region on a side of the one surface opposite to the side of the electrode, in which a depth dimension of a second recess portion defined by a mesa adjacent to the second region among the mesas of the plurality of light emitting units and the second region is larger than a depth dimension of a first recess portion defined by two mesas adjacent to each other among the mesas of the plurality of light emitting units.
