英文摘要The present invention provides for the coupling of laser diodes into electromagnetic radiation fibers wherein coupling efficiency is improved by improving the spatial brightness of multi-mode diode lasers as they are coupled into double-clad fibers. A Bragg grating (100) is fabricated into the core (102) of a double-clad fiber (104) coupled to a multi-mode diode laser (106). The output (108) from the multi-mode diode laser (106) is coupled into the core (102) and inner cladding (110) of the double-clad fiber by proximity or by one or more focusing objectives (112). The Bragg grating (100) in the core (102) of the double-clad fiber (104) is written at the wavelength of the multi-mode diode laser (106). The original output (108) from the multi-mode diode laser (106) strikes the Bragg grating (100) which reflects feedback (114) back to the diode laser (106).
