He - Ne LASER || PRINCIPLE, CONSTRUCTION, WORKING, ENERGY LEVEL DIAGRAM OF HELIUM NEON LASER ||

ABOUT THE VIDEO
**********************
He-Ne laser was the first gas laser fabricated by ALI-JAVAN & his co-workers in 1961.
Main features of this laser are:
1.It is a four level laser.
2.It is more reliable & easy to construct.
3.It does not require cooling arrangement.
4.It employes electrical pumping.
5.It works in continuous mode.
6.It is more directional, more coherent, more monochromatic than solid state lasers.
