Abstract
Systems and methods for mounting and aligning a laser in an electrically assisted magnetic recording (EAMR) assembly are described. In one embodiment, the invention relates to a submount assembly for a laser diode of an EAMR head, the submount assembly including a submount including a block shape including a first surface including a plurality of first conductive pads and a second surface including a second conductive pad, a laser including a main emitter and at least one alignment emitter, the laser having a block shape having a first surface including a plurality of first conductive pads attached to the first pads of the submount, and a slider including a top surface having a conductive pad configured to be attached to the second pad of the submount, wherein the at least one alignment emitter is configured to align the laser and the slider for attachment.
