Abstract
A diode laser apparatus includes an optical fiber having a multi-mode inner cladding and a core, the core having a fiber Bragg grating disposed therein, a plurality of diode lasers configured to emit light, and optics configured to receive the light and to couple the light into the optical fiber, wherein a portion of the light coupled into the optical fiber is reflected by the fiber Bragg grating and is coupled back through the optics into the diode lasers so as to lock the wavelength thereof.
