摘要： A laser source includes a laser device configured to emit laser light at a given angle with respect to a normal of an output end face; and an optical device configured to include an optical waveguide that guides and outputs the laser light. The output end face of the laser device is parallel to an input end face of the optical device, and the optical waveguide extends in a direction of θw1 that is given by θw1=arcsin(sin θa1/nF), where θa1 denotes an outgoing angle of the laser light from the laser device, and nF denotes an effective refractive index of the optical waveguide for the laser light.
