ABSTRACT:
The holographic element of the present invention includes a holographic grating pattern that is impressed in the media of the element utilizing beams of electromagnetic energy of wavelength .lambda..sub.o. The holographic grating pattern is capable of manipulating a beam of electromagnetic energy having a wavelength .lambda..sub.c at which the media is not necessarily suitable for recording. The method for manufacturing the holographic element utilizes an object beam and a reference beam having aspherical wavefronts of wavelength .lambda..sub.o to create the grating pattern in the media. In the preferred embodiment, the aspherical object beam and reference beam are created utilizing parent holographic devices recorded with spherical beams. An alternative embodiment of the present invention is a doublet holographic device which incorporates two holographic elements that are formed in accordance with the present invention to manipulate a beam of electromagnetic energy of wavelength .lambda..sub.c in a desired manner. The invention is particularly useful in obtaining high-quality volume phase holograms for use outside of the blue-green spectral range. A particular application is manipulating beams of electromagnetic energy from infrared laser diodes.
