Abstract
PURPOSE:To obtain a stable oscillation for a returning light by discovering an output light from the end face of an external resonator. CONSTITUTION:A light generated by implanting a current between electrodes 6a and 6b is laser-oscillated with a photoconductive layer 4 as an external resonator. An output light L is produced from a lens 11 from a cleaved face 8b formed at one end of the layer 4, and coupled through an isolator 12 to a fiber or the like. The reflecting returning light of the remote or near end of the isolator 12 is largely attenuated by an attenuation at the end face 8b of the layer 4, an attenuation due to the propagation of the layer 4, and an attenuation due to the coupling of the layer 4 to an active layer 3, thereby performing a stable oscillation.
