Holography is a part of optical physics that deals with the capability of producing three-dimensional images using coherent light sources, namely lasers. Key phenomena in optical physics – interference and diffraction – are directly behind its remarkable characteristics. The main objectives of this work follow along two major lines: i) the development of experimental approaches for hologram production using simple and inexpensive setups, and ii) the production of holograms effectively capable of illustrating important optical instruments, physical principles and/or effects. This is for the purpose of engaging students in the study of Physics, and to reinforce the yet modest presence of optical physics (including interferometry) and modern physics in undergraduate physics courses in Angola. Here we present experimental results in hologram production obtained with a versatile setup based on a single-frequency diode-pumped solid-state laser. This is aimed at testing several hologram recording geometries and concepts prior to developing more simplified setups based on inexpensive diode lasers. We also highlight a set of published works on applied holography that show how interference and diffraction phenomena are vital to many fields of applied physics, and how holography can be applied in different areas of science, technology and industry.
