Abstract

See full text

An apparatus includes an auto-alignment laser configured to generate an auto-alignment laser beam. The apparatus also includes a spectral beam combiner having a diffraction grating. The diffraction grating is configured to diffract multiple input laser beams to produce a combined beam having a higher power or energy compared to the individual input laser beams. The diffraction grating is also configured to diffract the auto-alignment laser beam so that a portion of the auto-alignment laser beam co-propagates in a common direction with the combined beam. Wavelengths of the input laser beams and the auto-alignment laser beam may be selected such that portions of the input laser beams and the portion of the auto-alignment laser beam diffract from the diffraction grating in the common direction. The portion of the auto-alignment laser beam that co-propagates with the combined beam may include a higher-order diffraction of the auto-alignment laser beam from the diffraction grating.
