Lasers in Medical Diagnosis and Therapy provides an overview on medical lasers and laser systems as well as laser applications in medical diagnosis and therapy. Since it was written by physicists, it focusses on the physics and underlying mechanisms of laser diagnosis and therapy and thus initially covers the basics of laser light generation, a selection of the most important laser types and systems commonly used in medicine, and the principles of laser light guidance. The book should be used as a textbook for lectures, practice lessons and for the preparation of exams and addresses students, lecturers, and researchers in the fields of medical engineering and technology, medical physics, medicine and surgery, ophthalmology, dermatology, laser physics and development as well as optical engineering.
