Abstract
A laser diode module includes a laser diode device, an optical device like a single lens placed in front of the laser diode device for reflecting front radiation emitted from a front surface of the laser diode device, and a photodiode placed at the back of the laser diode device and displaced from an optical axis of an optical system which includes the laser diode device, for receiving reflected radiation from the optical device.
