For what is used a pulsed laser?
A pulsed laser is used in many different situations from hair removal to surgery. The frequency and wavelength of the pulse determines the suitability of the laser for each type of use.
How laser light is produce from a laser gun?
In short, Light Amplification by Stimulated Emission of Radiation. Now, to explain. In a laser, there is something called a MEDIUM. This is where the photons are made. In all substances, there are atoms. In the atoms, there are electrons. The electrons are on orbits around the nucleus of an atom. There are more than one orbitin each atom. The electrons are EXCITED by getting hit by photons. The electrons absorb the energy from the photons they are hit by. To be on a certain orbit, the electron needs to have a certain amount of energy. When an electron is hit by a photon, it GAINS ENERGY so is jumps up to another orbit, because it has too much energy to stay on it's normal orbit. The electrons, though, ALWAYS have to go back to their original orbit (a law of physics) and in doing so, it needs to release energy in the form of a photon. Mirrors focus the light and it then comes out of the gun. There are more factors, but they are complicated and I cannot explain them for now. The main thing is the Excitation of the electrons then the release of the photons.
What sends out a narrow intense beam of light?
Well... Most LEDs, Light Emitting Diodes, have a very narrow wavelength span, so they'd fit part of your question. However, they're not always that intense. So you're probably asking about a LASER.
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. ==============================
Is a laser light a type of light?
Yes. Laser light is special in that all the waves of electromagnetic energy are temporally and spacially coherent i.e. the waves are in step (or in phase) with each other and travel in a thin beam which does not diverge over distance.
Can you change the color of a laser pointer?
No. Each laser pointer uses a laser that emits a specific color. the only way to get a different color would be to get a different laser.

What sort of businesses offer laser facials?
There are a number of businesses that offer laser facials. American Laser, Nolan Electrolysis, Cutera, and Laser Image Skin Care, for example, each offer this service.
In salon, What kind of laser they are using for hair removal?
There are actually multiple laser types used to remove hair. They are, pulsed light laser, diode laser, ND: Yag laer, alexandrite laser, and ruby laser. Here's a site that has information on each type: http://www.laserhairremovalreview.com/
What nicknames did royalist and puritan give each other and explain why?
The Royalists were also called Cavaliers, and the Puritans were called Roundheads, because of their short haircuts.
How do you chenge powder in laser printer?
The toner powder in a laser printer is sealed inside a toner cartridge, and it is the wholecartridge that is replaced. A mono laser has a single cartridge, while a colour laser will have a cartridge for each colour.
For what is used a pulsed laser?
A pulsed laser is used in many different situations from hair removal to surgery. The frequency and wavelength of the pulse determines the suitability of the laser for each type of use.
Where can one find information about laser marketing online?
One can learn about laser marketing through various groups, such as the Laser Marketing Group or USA Laser Marketing, respective divisions in their field of study. Each organization offers introspective analysis of the process in laser marketing and how it ultimately pays off.
