Holographic optical elements (HOE) for semiconductor lasers

Author(s) : Herzig, Hans-Peter
Description : A two step method is described to produce off-axis holographic lenses with high diffraction efficiency and without astigmatism for semiconductor lasers. The hologram is recorded in the visible (514 nm) and reconstructed in the infrared (800 nm). The principal parameters (recording and reconstruction...
