Synopsis:

In the course, the student will learn about the use of laser radiation in medical applications for diagnosis and treatment. In the introductory lectures, they will learn about the principle of the laser, its main parts and parameters. An overview of laser systems and their use in medicine will be given. He will acquire basic knowledge about the interaction of laser radiation with tissue, their division into primary and secondary factors. At the end, they will be introduced to specific applications of lasers in medicine.
