gaaslaseri tüüp, mille kõrge energeetilise keskmise võimenduskeskkond koosneb heeliumi ja neooni vahekorrast (5:1 kuni 20:1) kogurõhul ligikaudu 133 Pa väikese elektrilahenduse sees
type of gas laser whose high energetic medium gain medium consists of a mixture of ratio (between 5:1 and 20:1) of helium and neon at a total pressure of approximately 133 Pa inside a small electrical discharge
The best-known and most widely used the helium-neon laser laser operates at a wavelength of 632,8 nm (in air), in the red part of the visible spectrum.
