PROBLEM TO BE SOLVED: To provide a laser element with a multilayer reflector for suppressing multi-mode oscillations. SOLUTION: The vertical resonator type surface emitting laser includes a first mirror 1002, a resonator 1000 including an active layer, and a second mirror 1010 that are laminated. The second mirror 1010 is a multilayer reflector formed of a first layer 1014 and a second layer 1012 that are alternately plurally laminated, the second layer having a refractive index higher than that of the first layer. At least one of the second layers 1012 has an oxidization constriction structure having an oxidized region and a non-oxidized region. COPYRIGHT: (C)2009,JPO&INPIT
