Měření a zpracování charakteristických parametrů laseru

Abstract

This diploma thesis is concerned with the construction and the function of laser, thesis is also concerned with lasers used in medical therapy, safety and legislation used when working with therapeutic lasers. The practical part of the thesis is focused on the design of the measurement of characteristic parameters of therapeutic lasers by using CCD detector Spiricon SP503U and affordable and simple methods of measurement, which could find application in the process of teaching in the branch of Biomedical engineering. For this purpose, was created a laboratory task that enables future students of Medical therapeutic device familiarization with laser devices used for therapy and their characteristics parameters, which include the profile beam, beam power, the power density, the beam width, divergence of the beam, the wavelength, the length of the pulse and beam quality factor M2.
