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 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?
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 emitted during beta decay?
During beta decay, a beta particle (either an electron or a positron) is emitted from the nucleus of an atom. This emission occurs when a neutron in the nucleus is transformed into a proton, with the accompanying release of a beta particle and an antineutrino (in the case of beta-minus decay) or a neutrino (in the case of beta-plus decay).
Mercury-201 undergoes positron emission?
In positron emission, a proton in the nucleus is converted into a neutron, leading to the emission of a positron and a neutrino. Therefore, in the case of Mercury-201 undergoing positron emission, the nucleus transforms into a new element with one less proton and one more neutron in its nucleus.

Two examples of spontaneous combustion?
The first case of spontaneous combustion was documented in the 1400 after a man drank wine that made him spit vomit. A countess in 1700 also exploded and was found between her window and bed.
What reaction occurs when uranium atoms are split?
In such a case nuclear fission occurs.
Mercury-201 undergoes positron emission?
In positron emission, a proton in the nucleus is converted into a neutron, leading to the emission of a positron and a neutrino. Therefore, in the case of Mercury-201 undergoing positron emission, the nucleus transforms into a new element with one less proton and one more neutron in its nucleus.
If an organism is green how does it get food?
It depends on the type of organism. In the case of plants, many of which are green, photosynthesis occurs. In the case of some animals, like certain frogs, ingestion occurs.
A boating accident occurs In which case must the accident be reported to the Illinois Department of Natural Resources?
When a death occurs
How to get an extension on emission test?
You would need to contact the local Department of Motor Vehicles (DMV) or relevant authority to request an extension on your emission test. Explain your situation and provide any necessary documentation to support your request. Extensions are typically granted on a case-by-case basis, often for valid reasons such as being out of town or experiencing a medical emergency.
Is myopia a refraction disorder?
Yes. It usually occurs as the result of an elongated eyeball. In this case, the focal point occurs in front of the retina.
