Great video. I have one question though, how come heavy Ne atoms gets excited by light He atom ? And eventhough the energy levels are at same level, does not it means Ne atoms will also require same amount of energy to gets excited because obv He atoms will only dissipate energy equivalent to what they have absorbed as a result of exvitation.

I always think that lasers are useful (too) because of the energy they create. But how much is the net gain?
@EngineeringPhysicsbySanjiv
@EngineeringPhysicsbySanjiv 3 жыл бұрын
Energy is not created. It is converted from one form to other. The efficiency of laser is very low..

Why metastable state has more life time than other excited state?
@EngineeringPhysicsbySanjiv
@EngineeringPhysicsbySanjiv 2 жыл бұрын
It is just the lack of efficient processes for depopulating a certain level. For example, spontaneous emission may be prohibited by selection rules, i.e., by certain symmetries of wavefunctions.

Then photons wont be reflected back, all photons will be transmitted and amplification will stop. So laser beam will not be intense..

when spontaneous emission takes place between E3 to E2 in Ne atom, then what is the role of emitted photon.
@EngineeringPhysicsbySanjiv
@EngineeringPhysicsbySanjiv 2 жыл бұрын
spontaneous emission results into releasing the energy in the form of a photon, which is emitted in a random direction and does not contribute in light amplification.
