Nitrogen laser

A nitrogen laser is a type of laser that uses excited nitrogen molecules to produce light. When electricity energizes these molecules, they reach a higher energy state. As they return to normal, they emit a quick burst of ultraviolet light, typically at 337 nanometers. This laser generates very short, intense pulses of light and is often used in scientific research and specialized applications like laser spectroscopy. Its operation relies on a gas-filled tube, where electrical energy creates the conditions for the nitrogen molecules to emit these powerful, precise light pulses.
