摘要	A method and apparatus for combining a plurality of laser beamlets to form a single annular beam using spectral beam combination. This invention includes a plurality of laser sources that emit a plurality of beamlets, wherein each one of the plurality of beamlets has a different wavelength; a beam annularizer that includes a plurality of optical units arranged to receive the beamlets, and configured to convert each beamlet into a respective annular beam that has an annular cross-sectional power profile; a beam-intersection transform element configured to point each respective one of the plurality of annular beams in an angular intersection arrangement toward a first location; and a spectral beam combiner at the first location configured to combine the plurality of wavelengths in the plurality of annular beams into a first annular spectrally combined beam.
其他摘要	一种使用光谱光束组合组合多个激光小光束以形成单个环形光束的方法和装置。本发明包括发射多个子束的多个激光源，其中多个子束中的每一个具有不同的波长;一种光束环形化器，包括多个光学单元，用于接收小光束，并配置成将每个小光束转换成具有环形横截面光焦度轮廓的相应环形光束;光束相交变换元件，被配置为将多个环形光束中的每个相应的一个以角度交叉布置指向第一位置;第一位置处的光谱光束组合器，被配置为将多个环形光束中的多个波长组合成第一环形光谱组合光束。
主权项	A system for combining a plurality of laser beamlets to form a single annular beam using spectral beam combination, the system comprising: a plurality of laser sources that emit a plurality of beamlets, wherein each one of the plurality of beamlets has a different wavelength; a beam annularizer that includes a plurality of optical units arranged to receive the beamlets, and configured to convert each beamlet into a respective annular beam that has an annular cross-sectional power profile; a beam- intersection transform element configured to point each respective one of the plurality of annular beams in an angular intersection arrangement toward a first location; and a spectral beam combiner at the first location configured to combine the plurality of wavelengths in the plurality of annular beams into a first annular spectrally combined beam.
