Summary:A method and system for providing an energy assisted magnetic recording (EAMR) head are described. The EAMR head includes a laser, a slider, and an EAMR transducer. The laser has a main emitter and at least one alignment emitter. The slider includes at least one alignment waveguide, at least one output device, and an air-bearing surface (ABS). The alignment waveguide(s) are aligned with the alignment emitter(s). The EAMR transducer is coupled with the slider and includes a waveguide aligned with main emitter. The waveguide is for directing energy from the main emitter toward the ABS.
