because The xenon flash tube comprises a hermetically sealed glass tube, which is filled with a noble gas, usually xenon, and electrodes to carry electrical current to the gas. Additionally, a high voltage power source is necessary to energize the gas. A charged capacitor is usually used for this purpose so as to allow very speedy delivery of very high electrical current when the lamp is triggered

Difference between he-ne laser and ruby laser?
1.he-ne laser is gaseous state. Ruby is solid state laser. 2.he-ne laser requires electrical pumping. ruby laser requires optical pumping. 3.he-ne laser has 4 energy levels. ruby has 3 energy level. 4.he-ne laser gives continuous output. ruby laser gives output in form of pulse 5. he-ne laser is cheaper
Why He-Ne laser is continuous?
he ne laser has emmisions due to atleast three diffrent levels leading to three diffrent wavelenght of photons emitted..also as opposed to ruby laser which uses xenon flash tube , which gets highly heated and cant be used continously to exite the elctrons , a he-ne laser uses a high potential source like a tesla coil wich can be used continuously..
How does a xenon light bulb produce light?
Xenon light bulbs work from low pressure vapor. Like street lamps and stadium lights. The vapor is used to produce an ultraviolet light that arouses a phosphor coating in the tube.
How do you explain the characteristics of laser beam?
Laser beams are normally characterized as focused (the beam size enlarges slowly with distance), intense (don't look into a laser beam), and mono-energetic (single-color light). What is laser? -- laser stands for "light amplification by stimulated emission of radiation." What is being stimulated in laser? -- gas, solid-state, semiconductor, dye, chemical etc. Each type of laser has its own characteristics and pros and cons. The origin of laser radiation in a gas laser -- take a gas laser, for example. Argon gas is trapped inside a pressurized tube (low pressure to be exact). The tube's curved wall is coated with metal for reflection. Two flat mirrors are situated at each end of the long cylinder. Energy, in the order of kilowatts, is supplied to ionize the Argon gas. The excited Argon atoms will relax to release light in a very narrow spectrum, in the order of Watts -- very inefficient indeed. The mirrors and shiny curved wall are to keep the light generated to be trapped inside the tube intentionally, so that the lasing action can be amplified. The mirror at the "business" end has a small opening to allow light to escape. Hence the exiting laser beam is more or less uni-directional (focused). The light coming out of an Argon gas ranges from red to UV, but a filter at the exit can narrow the spectrum further to mono-chromatic. The filtered single-frequency light has little dispersion (photons will be traveling at about the same speed and few interference). The light is so intense and concentrated (~ 1 W over a beam size of 0.1 cm^2) that looking into a laser beam is detrimental to your eyes. Looking into a key-chain laser is not advisable either. Please see the related link for more details. ==============================

How does a camera flash work?
With older cameras, flashbulbs or flash cubes were used. Then, strobes were developed that used a flash tube. This gave almost limitless flashes. These work by using a battery to charge a capacitor. When the voltage on the capacitor is high enough, it is fed to a xenon (or similar) flash tube, which then fires, giving a very short duration, high intensity flash. It then takes a small amount of time for the capacitor to recharge, before it is ready for the next flash. Some cameras use a dual flash, which has an LED flash as well as a xenon flash.
What is the meaning of the acronym XLT?
XLT has many different meanings. Some of them include Microsoft Excel Template, Xerox Lexical Technology, Xenon Laser Tube, and Extra Large Telescope.
What raw materials are used to make a laser?
It depends on the type of laser you have in mind. Building lasers is technically very demanding. For example, in a crystal laser like a ruby laser, you would need a perfect ruby crystal (hence man-made), ground to perfect flatness and parallelism on each end, with tolerances within about a quarter wavelength of the laser's output. You need to be able to coat one end with a reflective mirror surface (facing the inside of the crystal) and the other with similar but only partially reflective surface. This process alone demands very precise control of the density. Then you need a Xenon flash tube of specific output and shape to encircle the crystal, capacitors sufficient to store the charge necessary to activate the tube, and control circuitry. The problems are similar with gas lasers. If you plan to build your own, you'll need glass-blowing skills and a furnace; you'll need means of setting reflective surfaces in the tube to within a perfect parallelism (quarter wavelength tolerances again), a source for the particular gas (helium, neon, carbon dioxide, etc) that you intend to use; a power source and control circuitry, and, of course something to house it in.
How does the laser works?
The laser works by reflecting and amplifying a beam of light through a tube of mirrors.

What is short time current?
instantaneous current transient current inrush current Photoflash Uses a Xenon tube in parallel with a capacitor capacitors in the hand held variety of photo flash are charged slowly with some sort of battery and oscillator when the capacitor is charged to 600V or so it is ready to discharge there will be an ignition coil to ionize the Xe when the Xe starts to completely ionize In a 1" long tube its resistance fall from near infinity to 1/2 Ohm This is about 1200 Amps those little cameras use #20 wire the average current is well below 1 amp to figure the wire size i^2 * R is not so significant more easily approximated as I^2*t you figure the amount of power with I^2*r and the amount of time this times the mass of the wire tells you how long it will take for the wire to melt witch is how fuses work photoflash the wire made from Xenon molecular wt 54 takes a while to heat to 9000K or so and to take pictures we like the black body spectrum rather than the bright bands in the uv its very near sunlight This takes about 1 millisecond the flash tube for a ruby laser is usually krypton wt 32 this heats much faster the flash lasts for about a 1 Microsecond this flash runs the ruby up to those higher energy levels then as a few discharge and trigger others this happens in about 1Nanosecond A short time
