发明名称 Apparatus for providing a stabilized laser source
摘要 Apparatus is provided for an improved stabilized laser source comprising a laser source having a light beam output and an electrical input. An optical waveguide, such as an optical fiber, having an input end is optically coupled to the laser source to receive the light beam. A reflector in the optical fiber, such as a fiber grating, reflects a portion of the light beam output back into the laser source. The reflector is provided at a distance from the laser source permitting the laser source to switch between states of coherence and coherence collapse of operation. The electrical input of a drive signal for the laser source includes a modulated signal with variations in amplitude to the electrical input to control the variation in switching between the states of coherence and coherence collapse of the laser source so that continuous laser operation remains kink-free. The optical waveguide provides the laser source light beam output to an optical gain medium having an excited state of operation of duration equal to a relaxation time wherein intervals between the variations of drive current amplitude modulation are less than the relaxation time of the excited state of the optical gain medium.
