Claim 10:
11. An apparatus, comprising:
a slider configured to facilitate heat assisted magnetic recording (HAMR);
a laser diode disposed in the slider;
a read element and a write element respectively situated at an air bearing surface (ABS) of the slider;
a near-field transducer (NFT) situated at the ABS proximate the write element;
an optical waveguide configured to couple light from the laser diode to the NFT;
a heater comprising a resistive element disposed in, along, or adjacent the laser diode; and
a controller coupled to the slider and the laser diode, the controller comprising:
a laser control coupled to the laser diode and configured to control operation of the laser diode; and
a heater control coupled to the heater and configured to control operation of the heater, the heater control configured to control the heater to heat the laser diode during at least a portion of a non-lasing state of the laser diode and at least a portion of a lasing state of the laser diode.
