Optical arrangement for use in laser for spectroscopic purposes, has flanks that are designed such that for wave length of light source, orthogonal interference pattern has integer multiple of interference periods on flanks

摘要

The optical arrangement has a light source for emitting the coherent light of a wavelength, and an optical lattice is provided with multiple diffraction structures arranged along a base area. The individual diffraction structures have a blaze-flank and an antiblaze-flank. The flanks are designed such that for the wave length of the light source, the orthogonal interference pattern has an integer multiple of interference periods on the flanks. The orthogonal interference pattern is formed by the interference of the incident light waves and the respective waves reflected on each flank.
