The wavelength of a helium-neon laser is typically 632.8 nanometers.
The wavelength of a helium-neon laser is determined by the energy levels of the electrons in the helium and neon atoms. When the electrons transition from higher energy levels to lower energy levels, they emit photons with a specific wavelength.
Yes, the wavelength of a helium-neon laser can be adjusted by changing the amount of energy supplied to the gas mixture, which in turn affects the energy levels of the electrons.
The wavelength of a helium-neon laser determines the color of the laser beam. It also affects the laser's ability to interact with certain materials and its overall effectiveness for certain applications.
The wavelength of a helium-neon laser is longer than that of other common lasers, such as ruby or argon lasers. This longer wavelength makes helium-neon lasers useful for applications that require a lower amount of energy, such as barcode scanners and laser printers.
