Today, the number of people interested in laser knowledge in medicine has increased dramatically Many practitioners and practitioners use this technology to improve the quality of treatment and diagnose patients. This book is due to provide short, practical tutorials for general and specialist undergraduates, and Fellowship students and laser educators and others interested in applying laser knowledge to their medical and research work. The book can do little to help those in need. At the end, the Honorable President of the Center for Laser Applications Research in Medical Sciences and my dear Professor Mohammad Reza Razzaghi, have been instrumental in editing this collection and I sincerely thank and appreciate the scholar press publications. Dedicated to you great Lord That light the heavens and the earth Dedicated to my mother and my father And to all the professors and patients who I have learned medicine and lasers from their teachings on their bedside.
