Abstract

PURPOSE:To stabilize the laser output by detecting the intensity of the light propagating into the fiber through measurement of the resistivity of the photoconductive film provided on the surface of the fiber incident end of in the propagation line and the feeding the detection output back to the driving circuit to control the laser output.
