ABSTRACT:
The laser device of the present invention includes a high-power, fiber-coupled optical source (FIG. 1) having a broad area laser diode (10) with a high reflective coating at its rear facet (12), coupling optics (20), and an optical fiber (30) having fiber grating (32). The fiber grating (32) serves to reflect a portion of the optical beam back to the broad area laser diode (10), thereby stabilizing the wavelength of the optical beam. The fiber grating (32) and the rear facet (12) of the broad area laser diode (10) serve as nodes for an external resonator, thereby limiting the diffraction of the optical beam. The effects of wavelength fluctuation and beam diffraction are reduced together using minimal mechanical components.
