Question

What is optical pumping​

Answer 1

Answer:

Optical pumping is a process in which light is used to raise electrons from a lower energy level in an atom or molecule to a higher one. It is commonly used in laser construction to pump the active laser medium so as to achieve population inversion.

Answer 2

Answer:

Optical pumping involves use of an auxiliary source of light that is absorbed by the active medium to raise electrons to high-lying energy levels. This has already been mentioned in reference to Figure 1-11. The ruby laser (see Figure 1-9) employs optical pumping to produce a population inversion..
