ABSTRACT:
An optical pulse generating apparatus having a semiconductor laser medium and an external resonator comprising an optical waveguide path. A reflecting element in the optical guide path is given such a reflection wavelength characteristic as to suppress other components than the component of an oscillation main longitudinal mode, so that the level of the main longitudinal mode component is raised and optical pulses with a narrower spectrum width and pulse width are produced.
