What Is a Nitrogen Laser?
A nitrogen laser is a type of laser that generates light using nitrogen gas.
This laser functions by electrifying nitrogen gas, which causes the gas molecules to absorb energy and subsequently emit light upon releasing that energy. Although nitrogen lasers are predominantly known for producing light in the red spectrum due to their intrinsic properties, they can emit light across a broad spectrum of wavelengths, from the visible to the near-infrared region.
Operated typically in a pulsed mode, these lasers are distinguished by their brief pulse durations, which facilitate the production of light pulses with high energy density. Nitrogen lasers are utilized in various domains, including high-speed laser processing and medical laser surgery, owing to their benefits such as high power output, versatility in wavelength generation, and cost-effectiveness.
