Helium-neon laser beam) is a type of laser beam that is produced by a helium-neon gas mixture. This type of laser is commonly used in scientific research, telecommunications, barcode readers, and laser printers.
The He-Ne laser beam operates in the visible spectrum, typically emitting red light at a wavelength of 632.8 nanometers. It produces a coherent, monochromatic, and low-power beam of light.
The beam is created by passing an electrical current through the gas mixture, which excites the helium and neon atoms. As these atoms return to their ground state, they emit photons of light, which are then amplified and reflected by mirrors within the laser cavity. The beam is emitted through an aperture in one of the mirrors, resulting in a highly collimated and focused beam.
He-Ne laser beams have a number of properties that make them useful in various applications. They have a long coherence length, meaning that the light waves remain in phase over a long distance. This property allows for precise interferometry and holography measurements.
Additionally, He-Ne laser beams have a narrow linewidth, meaning that the emitted light is of a specific wavelength. This property makes them ideal for applications that require precision, such as spectroscopy.
Furthermore, He-Ne laser beams have a low power output, typically ranging from a few milliwatts to a few watts. This makes them safe for use in scientific experiments and other applications where high power lasers may be hazardous.
In conclusion, a He-Ne laser beam is a red, coherent, monochromatic, and low-power laser beam produced by a helium-neon gas mixture. It is used in a variety of applications due to its long coherence length, narrow linewidth, and low power output.
