OPTICAL MODULE WITH DOUBLE EMITTER CHIPS AND DOUBLE DOVE PRISMS

An optical module may include a diode laser with dual emitters respectively configured to emit a first laser beam and a second laser beam in a beam propagation direction. The optical module may include a fast axis collimator (FAC) arranged to collimate the first and second laser beams in a vertical direction relative to the beam propagation direction and a slow axis collimator (SAC) arranged after the FAC to collimate the first and second laser beams in a horizontal direction relative to the beam propagation direction. The optical module may include a pair of Dove prisms between the FAC and the SAC, with respective axes rotated relative to the first emitter and the second emitter such that the first laser beam and the second laser beam swap fast and slow axes and are stacked in a fast axis direction after passing through the Dove prisms.
