摘要	A multimode-fiber Raman laser includes a pump source configured to provide optical radiation centered at a pump wavelength and characterized by a spectral bandwidth greater than 100 MHz and an oscillator resonant at an emission wavelength greater than the pump wavelength. The oscillator includes an input coupler optically aligned with the pump source and a multimode optical fiber optically coupled to the input coupler. The multimode optical fiber includes an input section having a fiber Bragg grating, an intracavity section of a predetermined length optically coupled to the input section, and an output section having a fiber Bragg grating. The oscillator also includes an output coupler optically coupled to the multimode optical fiber and configured to provide a laser output at the emission wavelength.

主权项	A multimode-fiber Raman laser comprising: a pump source configured to provide optical radiation centered at a pump wavelength λp and characterized by a spectral bandwidth greater than 100 MHz, thereby inducing negligible stimulated Brillouin scattering; andan oscillator resonant at an emission wavelength λn greater than the pump wavelength, the oscillator including: an input coupler optically aligned with the pump source; anda multimode optical fiber optically coupled to the input coupler, the multimode optical fiber comprising: an input section having a fiber Bragg grating characterized by a first predetermined reflectance at the emission wavelength; an intracavity section of a predetermined length optically coupled to the input section, the intracavity section being subjected to a Stimulated Raman Scattering (SRS) process thereby enabling power generation at arbitrary wavelengths; and an output section having a fiber Bragg grating characterized by a second predetermined reflectance at the emission wavelength and optically coupled to the intracavity section; and an output coupler optically coupled to the multimode optical fiber and configured to provide a laser output at the emission wavelength.
