An apparatus comprises a slider configured to facilitate heat assisted magnetic recording. The slider comprises a plurality of bond pads including a first electrical bond pad, a second electrical bond pad, and a ground pad. A laser diode comprises an anode coupled to the first electrical bond pad and a cathode coupled to the second electrical bond pad. The laser diode is operable in a non-lasing state and a lasing state. A heater is coupled between the ground pad and at least one of the anode and cathode of the laser diode. The heater is configured to generate heat for heating the laser diode during the non-lasing state and the lasing state.
