Claim:
1. A method for producing a laser diode, the method comprising: forming a plurality of laser diodes on a wafer; separating the wafer into wafer pieces, each wafer piece comprising a plurality of laser diodes arranged side by side; inserting one wafer piece into a first mount, the first mount comprising a first covering element overlapping a front face of the wafer piece and shadowing a bottom area of the front face of the wafer piece; depositing a mirror layer only on an unshadowed upper area of the front face of the wafer piece; inserting the wafer piece into a second mount, the second mount comprising a second covering element, the second covering element shadowing the mirror layer of the upper area of the front face; depositing an electrically conductive contact layer on an unshadowed bottom area of the front face of the wafer piece; and separating the wafer piece into individual laser diodes.
