What are different methods to contain photon energy inside a large amount of atoms (stimulated emission)?

Notwithstanding quantum mechanical effects from quantum field theory involved in photons escaping confined regions that I'm not qualified to answer in regards to, and supposing that you had *ideal* mirrors that reflected all of the incident energy of the photon and if you could seal the box (or probably a better aparatus would be a sphere) before your incident light beam escaped, then I believe the answer is yes.\n\nI'm fairly sure that this is not quite as theoretical as I've made it sound by invoking ideal mirrors and actually is practical.  I'm fairly sure that there is a research group here at my University working on storing information encoded in photons by basically trapping it between two mirrors to bounce back and forth until released for further processing.  I haven't been able to find a link to any research publications on that, but I'll update you if I locate one.\n\nI hope that helps.

The achievement of a significant population inversion in atomic or molecular energy states is a precondition for laser action. Electrons will normally reside in the lowest available energy state. They can be elevated to excited states by absorption, but no significant collection of electrons can be accumulated by absorption alone since both spontaneous emission and stimulated emission will bring them back down.\n\npopulation inversion occurs when a system (such as a group of atoms or molecules) exists in state with more members in an excited state than in lower energy states. The concept is of fundamental importance in laser science because the production of a population inversion is a necessary step in the workings of a laser.

some radioactive form of light can penetrate,e.g. X-rays

Photons.\n\nI've heard of wavicles, but I think that sounds like a frozen dessert.

Light Amplification (by) Stimulated Emission (of) Radiation\n\nMany different types:\n\nRuby rod laser - basically a polished rod of aluminium oxide/chromium oxide (synthetic tuby), surrounded by apowerful flashtube.  - Visible Red\n\nNitrogen laser, co2 laser (gas lasers) fairly efficient by laser standards, inivisble output but can be strong enough to cut metal\n\nsemiconductor - both invisible and red - cheap for low power\n\ndpss  -  diode pumped solid state - these lasers use a "pump" diode which is usually 808nm, tis goes into a sliver of something called vanadate which take in light at 808bm (almost invisible Infra Red) and re-emit it at 1064nM (Invisible. It is then put through a crystal of KTP which halves the wavelength (doubling the frequency) and re-emits at 532nM - bright green

i think that you should try to make some working models of semi conductors and and their use in the LED as you will search for the led then you will find that how semi. cond. helped to enrich the fields of leds . and i think that either you can go with the working projet of radar and how they used . or on lasers. lasers is really an interestin field. and i don't have any idea bout the chems. go to the discovery kids.com site and you will thousand of project reports.

Hmm. . its pretty rare stuff so you are not going to hand out samples\nSince it was once used in lasers you could start your presentation with a laser light show, or just a simple laser pointer\nPresent the information chronologically, show how and why it was discovered (it started as a blank square on the Periodic Table of the Elelments) talk about it uses and why it was replaced\ngood luck

HAHAHAH ARE YOU TRYING TO TEST US?\n\nLight is a form of electromagnetic radiation: i.e. it has oscillating electric(E) and magnetic(B) fields that travel through  space at speed c with the same frequency and wavelength.\nrotational energy of light if I am not worng...I like that sh.t!!good question\nRotational energy level gaps typically\n\n \n\nDE = 10^-23 J\n\nTherefore n = 1.5 x 10^10 s^-1

Electromagnetic waves.  That includes x, gamma, visible light etc...\n\nGravitational waves.

A laser beam is coherent light, meaning the light waves vibrate at the same speed and reach crests and troughs at the same time, which makes the beam a  strong radiation, since radiation is just very energetic waves.  I guess it is pure light energy just in a modified form

There are a few items you will need:-\n1) A source of high voltage (to exicte the gas in your laser to emit photons). A readily availible item to do this would be the ballast (transformer) in a flourescent tube. This should get you up to between 700 to 1700 volts. It is preferabe if you have a supply closer to the upper end. This is dangerous so be sure to use appropriate precautions when working with high voltages.\n2) Choose the type of gas to excite. Gases to use include Carbon dioxide, helium, argon, neon, krypton - depending on the frequency you want from the laser. A nice big ruby could be used to make a really cool ruby laser - I could never afford to buy one though.\n3) build a laser tube - or better buy one from ebay. If you have glass blowing skills and make can make your own electrodes and embed them in the glass tube and make partial reflective mirrors on the end or the tube you can make one - but it's really tricky.\n4) fill your lser tube with the gas/gases you choose under reduced pressure.\n5) connect the electrodes to your power supply\n6) power it up....\nIt's as easy as that... uses the same basic principle to a flourescent tube, except that all the light from the partial reflector window is in phase.\n\nFor more detail I suggest you google something like "home made laser"

The energy contained within a single photon of light can be found using Planck's equations,\nE = hv\nWhere E is the energy, h is Planck's constant, and v is the frequency of the light.\n\nYou can see that the higher the frequency of light, the higher the energy per photon.\nExamining the spectrum of light one can see that green light (roughly a wavelength of 550 nm) has a higher frequency than orange light (roughly a wavelength of 650 nm).\nTherefore, green light photons contain more energy than orange light photons.\n\nPlanck's constant = h = 6.626 E-34 J s

A LASER (Light Amplification by Stimulated Emission of Radiation) is an optical source that emits photons.\nThe verb "to lase" means "to produce coherent light" or possibly "to cut or otherwise treat with coherent light", and is a back-formation of the term laser.

I don't think you can... A Laser Beam is just an intense form of light created by the stimulated emission of radiation (hence Light Amplification by Stimulated Emission of Radiation L.A.S.E.R).\n\nElectricity is the movement of electrons through a physical circuit, so can't see how it can be done via light.\n\nHowever obviously Lasers are used in many applications (telecoms, house hold stereos, CD Players etc)... the light is pulsed at a very high speed and these pulses are decoded into an electrical signal.\n\nHope that helps.

Yes, bombard it with neutrons and it will release energy...\n\nWill it be efficient.. NO. but you can do so.
