Lasers in Biomedicine

Code	13454
Year	3
Semester	S2
ECTS Credits	6
Workload	PL(30H)/T(30H)
Scientific area	Biomedical Sciences
Entry requirements	Not required.
Learning outcomes	The main goals of this course unit are to disseminate applications of lasers in medicine and the basic concepts of physical optics that allow their understanding. At the end of this course, the student should be able to identify and characterize several types of laser systems (and associated optics) for therapeutic applications. The student should be able to understand the biophysical mechanisms of interaction of laser light with biological tissues. The student should also be aware of the state-of-the-art laser applications in medicine in a national context.
