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 compressible heat-dissipating fin, a compressed heat-dissipating fin assembly, and a method for making a fin assembly for cooling an electromechanical device such as a transverse-flow forced air-cooled ion gas laser are disclosed. Each fin preferably has a slit running through its center except for a small hinge. The slit provides the fin with compressibility and increased contact pressure when the fin is fitted directly to and compressed against the tube, preferably by clamping, during the brazing cycle.
