In He-Ne laser, neon atoms are the active centers and have energy levels suitable for laser transitions while helium atoms help in exciting neon atoms. Electrodes (anode and cathode) are provided in the glass tube to send the electric current through the gas mixture. The linewidth (or line width) of a laser, e.g. a single-frequency laser, is the width (typically the full width at half-maximum, FWHM) of its optical spectrum. More precisely, it is the width of the power spectral density of the emitted electric field in terms of frequency, wavenumber or wavelength.

Each line has a natural line width and the Doppler effect and pressure effects broadened it even more. If the Doppler effect and pressure effects dominate the line width, the it will have a smooth Gaussian profile. Red He-Ne lasers typically have a full-width-at-half-maximum (FWHM) of 1400 MHz. The D4σ and knife-edge widths are sensitive to the baseline value, whereas the 1/e 2 and FWHM widths are not. The fraction of total beam power encompassed by the beam width depends on which definition is used.
