What is the difference between spontaneous emission and stimulated emission?
stimulated emission causes due to the energy difference between the higher and lower energy level state, but it doesn't depends in the case of spontaneous emission . spontaneous emission causes without any stimulation .In stimulated emission energy transfer is twice the energy transfer of spontaneous emission.
What is the difference between spontaneous and stimulated emission of light?
stimulated emission causes due to the energy difference between the higher and lower energy level state, but it doesn't depends in the case of spontaneous emission . spontaneous emission causes without any stimulation .In stimulated emission energy transfer is twice the energy transfer of spontaneous emission.
Difference between stimulated and spontaneous emission?
emissions is stmulated when a stimulus takes over them. Spontaneous emissions happens when the individual is very sensitive.
What are conditions required for laser action?
1. Population inversion should be achieved. 2. Stimulated emission should be predominant over spontaneous emission
Name three necessary condition for lasing action?
To get laser action 1)population inversion should be achieved to get stimulated emission.(ie)N2>N1 Where N1 and N2 are the number of atoms in level E1 and E2 respectively. 2)stimulated emission should be effective over than the spontaneous emission.

How can spontaneous emission be control?
That's why it's called spontaneous emission you cannot control it. But there is a kind of emission which is called stimulated emission emission. People use stimulated emission in lasers and it can be controlled.

What is the difference between spontaneous emission of radiation and stimulated emission of radiation?
The laser causes the stimulated emission of radiation. The light emitted is monochromatic and coherent,that is plane polarised. I imagine that spontaneous emission occurs in a Light emitting diode ,monochromatic but not polarised. Hope this is of help

What is Lase?
The lasing threshold is the lowest excitation level at which a laser's output is dominated by stimulated emission rather than by spontaneous emission.

Who invened lasers?
Well the principle of stimulated emission was discovered by Albert Einstein. But first laser was fabricated by Theodore Mainman
What is the physical significance of einsten coefficients?
They measure the probability (or rate) at which a photon is being absorbed through spontaneous absorption (the A coefficient), and also the probability at which a photon is being emitted through spontaneous and stimulated emission (the B coefficients).
Does 'maser' stand for molecular amplification by stimulated emission of radiation?
Microwave Amplification by Stimulated Emission of Radiation
