Introduction to CO2 Lasers

CO2 lasers are a type of gas laser that produces a powerful beam of infrared light. They are widely used in various industries due to their high power output, efficiency, and versatility. This section provides a comprehensive overview of CO2 lasers, covering their operating principles, key components, and diverse applications.

Operating Principles of CO2 Lasers

CO2 lasers operate based on the principle of stimulated emission of radiation. The laser medium is a mixture of carbon dioxide (CO2), nitrogen (N2), and helium (He) gases. When an electric current is passed through this gas mixture, the nitrogen molecules are excited to a higher energy level.

These excited nitrogen molecules then transfer their energy to CO2 molecules, causing them to become excited as well. The excited CO2 molecules then release photons of infrared light as they transition back to their ground state. This process is stimulated by the presence of other photons, leading to the amplification of the laser beam.
