An optical apparatus includes a first beam combining device arranged to receive a first optical beam having a first wavelength at a first location and a second optical beam output having a second wavelength at a second location. The second optical beam has a polarization that is substantially orthogonal to a polarization of the first optical beam. The first beam combining device configured to output a first combined beam that comprises a combination of the first optical beam and the second optical beam. An optical element is arranged to receive the first combined beam and a second combined beam and to transmit an output beam that includes a combination of the first combined beam and the second combined beam.

Device and method for optical beam combination

A method for diagnosing a faulty board includes generating a table of debug knowledge in accordance with predefined debug rules, and configuring a diagnostic engine in accordance with the table of debug knowledge. The method also includes subjecting the faulty board to the diagnostic engine to generate a suggested repair, receiving feedback regarding an effectiveness of the suggested repair, and reconfiguring the diagnostic engine in accordance with the feedback regarding the effectiveness of the suggested repair.
