Design of interferometric system for laser wavelength calibration

U današnje doba neophodno je poticati istraživanje i razvoj u području mjerenja i ispitivanja, izobrazbe i prijenosa znanja, te podići svijest o važnosti i preciznosti mjerenja i ispitivanja. Svjesnost toga je i poticaj istraživanja ovog rada; na temelju znanja stečenih u okviru studija izraditi interferencijski sustav za mjerenje valne duljine lasera s ciljem utvrđivanja valne duljine nepoznatog lasera po principu interferometrije za mjerenje pomaka. U ovom radu dan je općeniti pregled postojećih metoda i tehnika mjerenja valnih duljina kao i nekih komercijalno dostupnih sustava, te je na temelju njih i dostupne opreme obrađena i praktično provedena ideja izrade takvog sustava.Nowadays it is necessary to encourage research and development in the field of measurements and testing, training and transfer of knowledge and raise awareness of the importance and accuracy of measurements and tests. Consciousness about that is also the guiding principle of this paper; based on the knowledge gained within the study to develop an interference system for measuring wavelengths of lasers in order to determine the wavelength of an unknown laser based on the principle of displacement measuring interferometry. This paper presents a general overview of existing methods and techniques of wavelength measurement, as well as overview of some commercially available systems, and based on them and the available equipment, the practical idea of making such a system was carried out
