Question

example for creation of population inversion by optical pumping is​

Answer 1

Answer:

Optical Pumping

As the name suggests, in this method, light is used to supply energy to the laser medium. ... Hence, more electrons are accumulated in the energy state E2 than the lower energy state E1. Thus, population inversion is achieved. Optical pumping is used in solid-state lasers such as ruby lasers.

Answer 2

$\huge\boxed{\fcolorbox{white}{pink}{Answer:-}}$

The atoms of Ruby are excited with the help of photons emitted by an external optical source. The atoms absorb energy from photos and raises to excited state. Therefore Ruby laser is an example of optical pumping.
