Abstract
Some problems relevant to study and application of coherent light in the frame of advanced laboratory works (MSc study, programme Optics and Lasers) are presented in the paper. The attention is devoted to study and application of coherent properties of laser diode module (LDM), which became accessible in a relatively simply and inexpensive way [1]. The laboratory topics come from the former research having been conducted at our optical division [2, 3]. Fabry-Perot interferometry and diffraction by a suitable holographic grating (produced at the laboratory) are applied to demonstrate and study the coherence properties of LDM. A device based on Peltier cooling, developed at our division [4], is used to stabilize the coherence properties of LDM. This way improved LDM can be used for any coherent experiment (holography, interferometry, optical information processing...)
