Paper Abstract

Laser diode module (LDM) became a commonly used light source, even when the interference pattern has to be created. Nowadays, fabricating a holographic grating is relatively a simple procedure. The two-beam interference took an important role among all of its applications. Nevertheless, the parameters of the interference grating depend on properties of the light source and recording medium used. On the contrary, a holographic grating may become a simple and useful tool to reveal real temporal coherence properties of widely used LDM and to determine frequency spacing when more longitudinal modes are generated.
