A pad-fixed laser therapeutic apparatus and a laser emitter are provided. The laser therapeutic apparatus includes a power supply unit, a first electrically-conductive attachment unit and a second electrically-conductive attachment unit attached to an organism, a laser emission unit, an open-circuit detection control unit, and a processing unit. The laser emission unit is fixed on the organism through the first electrically-conductive attachment unit and the second electrically-conductive attachment unit. The open-circuit detection control unit is electrically connected to the first and second electrically-conductive attachment units. The processing unit is electrically connected to the power supply unit, the laser emission unit, and the open-circuit detection control unit. When the open-circuit detection control unit detects that a circuit is in an open-circuit state, the laser emission unit stops emitting a laser, to prevent a laser from irradiating the eyes of another person when the laser emission unit falls off.
