Harnessing the Power of Lasers for Medical Purposes

Introduction:

In recent years, lasers have emerged as a revolutionary technology with vast applications in the field of medicine. This article aims to explore the various ways that lasers are being utilized for medical purposes, from diagnostics to treatments. By harnessing the power of lasers, healthcare professionals are able to offer patients more precise, less invasive, and highly effective medical interventions.

I. Understanding Lasers in Medicine

1.1 What are lasers?

Lasers, short for Light Amplification by Stimulated Emission of Radiation, are devices capable of producing a concentrated beam of light. They emit light through a process of optical amplification and provide a consistent wavelength that enables accurate targeting.
