Question

which of the following is an example of optical pumping...(A)..ruby laser ..(B) helium -neon laser ..(C) semiconductor laser ..(D) dve laser​

Answer 1

A) Ruby Laser

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.

hope it helps..

Answer 2

The correct answer is OPTION A: Ruby Laser.

• Ruby's atoms are stimulated by photons emitted by an external light source.
• The energy from the images is absorbed by the atoms, which causes them to become agitated.
• As a result, the Ruby laser is an example of optical pumping.
• Optical pumping is a technique for moving electrons from a lower to a higher energy level in an atom or molecule by using light.
• Pumping the active laser medium to cause population inversion is a common laser-building practice.
