Abstract: A method of combining and co-aligning a plurality of radiation beams each having a respective waveband, includes the steps of passing each of said radiation beams to a respective lateral deflector to impart a selected lateral displacement to said beam. Each of said radiation beams with respective imparted lateral displacements is then passed to an optical collimating element which passes said radiation beams to an optical deflecting element which applies a wavelength dependent deflection to the radiation beams. The respective lateral displacements are selected having regard to the waveband of each beam to cause all to exit the optical deflecting element at the same angle so they are co-aligned.

Abstract: Techniques are disclosed for improving pump absorption and efficiency for fiber lasers and amplifiers, for instance. In some embodiments, the techniques are implemented by applying a partially reflective coating on a fiber end-face to double-pass any unabsorbed or otherwise excess pump light in the cladding of a fiber. While being reflective to pump wavelengths, the coating can be non-reflective at the lasing wavelength, so as to avoid unwanted feedback into the system. The benefits of this approach include that excess pump power can be effectively utilized to add more power to the laser output. In addition, the double-pass technique allows for the use of a shorter fiber length, which in turn allows for more compact system designs, saves on material costs, and facilitates manufacturability.
