Original Abstract Submitted
to prevent a decrease in oscillation efficiency of laser light and a decrease in conversion efficiency of an optical wavelength due to thermal interference. a laser element includes: a laminated 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 disposed on a rear side of an optical axis of the laminated semiconductor layer and including a second reflection layer with respect to a second wavelength on a first surface facing the laminated 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 disposed on the second surface or disposed on a rear side of the optical axis with respect to the second surface; a first resonator that causes light of the first wavelength to resonate between the first reflection layer and the third reflection layer; a second resonator that causes light of the second wavelength to resonate between the second reflection layer and the fourth reflection layer; and a heat exhaust unit that is disposed between the laminated semiconductor layer and the laser medium and exhausts heat generated in at least one of the laminated semiconductor layer or the laser medium.
