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.
What is the difference between spontaneous emission and stimulated emission?

Difference between stimulated and spontaneous emission?
Stimulated emission occurs when an already excited atom is triggered by an external photon to release a second identical photon. Spontaneous emission, on the other hand, happens when an excited atom releases a photon without any external stimulation.
How spontaneous emission occurs in case of lasers?
Spontaneous emission in lasers occurs when excited atoms or molecules in the lasing medium release energy in the form of photons. These photons have random phases and directions, which do not contribute to laser amplification. To achieve laser operation, the spontaneous emission needs to be amplified and synchronized through a process known as stimulated emission.
What short for light amplification by stimulated emission of radiation?
Laser is short of light amplification by stimulated emission of radiation.
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 and stimulated emission any 5points?
Spontaneous emission occurs randomly and naturally when an excited atom transitions to a lower energy state, releasing a photon in the process. Stimulated emission, on the other hand, is induced by the presence of external photons that cause an already excited atom to release a second identical photon. In spontaneous emission, the emitted photon may have any frequency within the spectral line width of the transition. In stimulated emission, the emitted photon has the same frequency, phase, direction, and polarization as the stimulating photon. Spontaneous emission is non-coherent and occurs independently of external radiation. In contrast, stimulated emission is a coherent process that contributes to the amplification of light in lasers. The rate of spontaneous emission is independent of the intensity of external radiation, while the rate of stimulated emission is directly proportional to the intensity of the stimulating radiation. Spontaneous emission plays a role in processes like fluorescence and phosphorescence, whereas stimulated emission is the principle behind the operation of lasers.
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.
What short for light amplification by stimulated emission of radiation?
Laser is short of light amplification by stimulated emission of radiation.
What is the scientific principle involved in a laser?
A laser operates based on the principle of stimulated emission of radiation. Stimulated emission occurs when a photon interacts with an excited atom, causing the atom to emit another photon that is identical in wavelength, phase, and direction to the first. This process leads to the coherent and intense light output characteristic of lasers.
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?
