In a method for producing a laser element, a brazing material is placed
between a nitride-based semiconductor laser bar and a fixation surface of
a heat sink, where the brazing material contains gold and one of tin and
silicon as main components, the nitride-based semiconductor laser bar has
at least three light-emission points formed on a substrate, the heat sink
is made of copper or copper alloy, and the fixation surface has a
predetermined shape. Then, the nitride-based semiconductor laser bar is
fixed to the fixation surface of the heat sink by melting and solidifying
the brazing material while pressing the nitride-based semiconductor laser
bar toward the heat sink with a tool having a shape corresponding to the
predetermined shape of the fixation surface.
