OPTICAL SLICER FOR IMPROVING THE SPECTRAL RESOLUTION OF A DISPERSIVE SPECTROGRAPH

摘要

A beam reformatter to receive and split a beam into a plurality of beam portions, and further distribute and propagate two or more of the plurality of beam portions in substantially the same direction to create a reformatted composite beam, wherein the plurality of beam portions each contain the same spatial and spectral information as the received beam. An optical slicer to receive and configure a beam for generating an output spot from the configured beam, comprising: a beam reformatter to receive and split a beam into a plurality of beam portions, and further distribute and propagate two or more of the plurality of beam portions in substantially the same direction to create a reformatted composite beam; and at least one of a beam compressor and a beam expander wherein the plurality of beam portions each contain the same spatial and spectral information as the received beam; and the output spot has different dimensions relative to a spot produced in the same manner from the beam received by the optical slicer.
