摘要： A waveguide includes a cladding region that has a refractive index that is substantially uniform and surrounds a wave-guiding region that has an average index that is close to the index of the cladding. The wave-guiding region also contains a thin ring or series of rings that have an index or indices that differ significantly from the index of the cladding. The ring or rings enable the structure to guide light.

摘要： An optical fiber amplifier includes a length of silica optical fiber having a core doped with neodymium, a first cladding and a second cladding each with succeeding lower refractive indices, where the first cladding diameter is less than 10 times the diameter of the core. The doping concentration of the neodymium is chosen so that the small signal absorption for 816 nm light traveling within the core is less than 15 dB/m above the other fiber losses. The amplifier is optically pumped with one laser into the fiber core and with another laser into the first cladding.

摘要： A system for lasing includes a diode laser array for emitting light of wavelength .lambda..sub.0, a tunable Bragg grating fiber laser connected to the diode laser array for emitting single mode light of wavelength 2*.lambda..sub.vis, a cladding pumped power amplifier connected to the diode laser array and the tunable Bragg grating fiber laser, and a second harmonic generator, including an optical cavity and crystal, connected to the cladding pumped power amplifier for emitting light of wavelength .lambda..sub.vis. The second harmonic generator is maximized, thereby maximizing emission of the light of wavelength .lambda..sub.vis, by control electronics connected to the tunable Bragg grating fiber laser, the cladding pumped power amplifier, and the second harmonic generator. The control electronics stabilize the amplitude of the light of wavelength 2*.lambda..sub.vis, emitted by the tunable Bragg grating fiber laser and lock the frequency of the light of wavelength 2*.lambda..sub.vis to the optical cavity resonance.
