Event Description: The special properties of lasers make them much better than sunlight or other light sources at targeting medical applications. Each laser operates within a very narrow wavelength range and the light emitted is coherent. They can also be very powerful. The beams can be focused to a very small point, giving them a high-power density. These properties have led to lasers being used in many areas of medical diagnosis and treatment.
Speaker: Dr. Y Aparna, Professor of Physics, Department of Physics, JNTUH College of Engineering Hyderabad.
