When light interact with matter, three processes may occur (a) absorption (b) spontaneous emission and (c) stimulated emission. "If we consider a He-Ne laser at normal equilibrium conditions laser we won't be able to achieve laser action in the optical range (n=400nm - 700 nm).” Explain this statement with the help of equations and give typical values to ascertain your argument?
