LASER ELEMENT AND ELECTRONIC DEVICE

A temperature rise in an optical resonator can be suppressed, or damage to the optical resonator due to laser light condensing can be avoided.A laser element includes a semiconductor layer including a first reflection layer with respect to a first wavelength and an active layer that performs surface emission at the first wavelength, a laser medium arranged on a rear side of an optical axis of the semiconductor layer and including a second reflection layer with respect to a second wavelength on a first surface facing the semiconductor layer and a third reflection layer with respect to the first wavelength on a second surface on a side opposite to the first surface, a fourth reflection layer with respect to the second wavelength arranged on the second surface or arranged on a rear side of the optical axis with respect to the second surface, a first resonator that causes light having the first wavelength to resonate between the first reflection layer and the third reflection layer, a second resonator that causes light having the second wavelength to resonate between the second reflection layer and the fourth reflection layer, and an optical element arranged between the second reflection layer and the fourth reflection layer, the optical element that increases a beam diameter of the light having the second wavelength, in which the optical axis of the semiconductor layer, an optical axis of the laser medium, and an optical axis of the optical element are coaxially arranged.
