What Are Helium-Neon Lasers?
Helium-Neon lasers, often referred to as HeNe lasers, are gas lasers that use a mixture of helium and neon gases to generate laser light. Typically emitting a red beam at a wavelength of 632.8 nm, these lasers have been widely utilized for their stable output, narrow spectral linewidth, and long operational lifetime. The HeNe laser tube is a central component of these lasers, providing the necessary environment for the gas mixture to become excited and produce coherent light.
HeNe lasers can operate in continuous wave (CW) mode, meaning they can emit a steady, uninterrupted beam of light. This quality makes them ideal for applications that require consistent light output over extended periods, such as in laboratory research, industrial measurement, and optical alignment tasks. Though newer laser technologies, such as diode lasers, have emerged, HeNe lasers remain a staple due to their reliability and performance.
