Abstract: 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.

Abstract: An apparatus includes an in-line reflective optical system configured to receive an input optical beam and provide an output optical beam. The in-line reflective optical system includes first and second powered mirrors aligned back-to-back. The first powered mirror is configured to reflect the input optical beam as a first intermediate beam. The in-line reflective optical system also includes first and second reflective surfaces respectively configured to reflect the first intermediate beam as a second intermediate beam and to reflect the second intermediate beam as a third intermediate beam. The second powered mirror is configured to reflect the third intermediate beam as the output optical beam. A spacing between the first and second reflective surfaces and the first and second powered mirrors is adjustable to control a focus of the output optical beam without introducing boresight error in the output optical beam.
