LASER is the acronym for "Light Amplification through Stimulated Emission of Radiation".
Helium Neon laser (or HeNe laser) is a gas laser. It consists of 85% helium and 15% neon. It is a cost effective and easy to use laser.
The light emitted from Helium Neon laser is highly monochromatic with a wavelength of 632.8 nm.

Hey buddy,
LASER stands for Light Amplification by Stimulated Emission of Radiation
# Helium-Neon Laser-
- Helium-Neon(He-Ne) laser is a type of small gas laser
- It is a 4-level laser
- It operates in continous working mode
- It was the first continuous laser
# Wavelength-
It's operational wavelength is 632.8nm in the red portion of visible spectrum.
# Applications-
- used in guns for targeting
- used for laboratory demonstration of optics
- used in holography for producing 3D images
- used in supermarkets to read bar-code
Think that was useful...
