Abstract:
1. A laser diode array comprising: a plurality of multi-cavity laser diode chips, each having a plurality of light emitting points fixed side by side; a plurality of collimator lenses; and a condenser lens, wherein the multi-cavity laser diode chips are arranged in a first direction which is the direction in which the light emitting points in each of the multi-cavity laser diode chips are arranged, a respective one of the plurality of collimator lenses is provided for each of the laser diode chips and is smaller in diameter of aperture in the first direction than in a second direction perendicular to the first direction, and the condenser lens condenses a plurality of laser beams, each of the laser beams collimated by the respective collimator lenses, and converges the laser beams on an end face of an optical fiber.
