摘要： To make miniaturization of a laser module easier. In the laser block of a laser module, multiple semiconductor laser elements that each emit a beam of laser light are disposed. A collimating lens receives and collimates the individual beams of laser light emitted from the laser block, and emits collimated light. Photodiodes detect the individual beams of collimated light emitted from the collimating lens, and output signals corresponding to the intensities of the individual beams of collimated light. Additionally, the photodiodes are disposed on the propagation paths of collimated light emitted from the collimating lens, and in addition, are disposed at positions that receive a portion of collimated light for all the individual beams of collimated light which are emitted.
