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. ==============================
What are uses for argon?
Argon is used in situations where materials need to be protected from oxygen or other gases. A good example is an incandescent light bulb, which consists of a metal wire inside a clear glass bulb. An electric current passes through the wire, causing it to get very hot and give off light. Oxygen will combine with the hot metal very easily, forming a compound of the metal and oxygen. This compound will not conduct an electric current very well, thereby causing the light bulb to stop giving off light. Argon, however, is used to prevent this from happening. Because argon is inert, it will not react with the hot wire, leaving the metal hot for very long periods of time. The light bulb will stop giving off light only when the metal breaks. Then it can no longer carry an electric current. Argon is also used in welding. Welding is the process by which two metals are joined to each other. In most cases, the two metals are heated to very high temperatures. As they get hot, they melt together.However, as the metals get hot, they begin to react with oxygen. In this reaction, a compound of metal and oxygen is formed. It becomes very difficult to join the two metals if they have formed compounds, but introducing argon into the welding environment improves the bond. Argon is also used in argon lasers and argon-dye lasers. A laser is a device that produces very bright light of a single color (frequency). An argon laser is used to treat skin conditions. The laser shines a blue-green light on the affected area of the skin. The energy from the laser is absorbed by hemoglobin and converted to heat. (Hemoglobin is the protein pigment in red blood cells. It transports oxygen to the tissues and carbon dioxide from them.) The blood vessels are damaged, but then sealed, prompting them to decompose and be reabsorbed into the body. Unwanted growths are flattened and dark spots are Lightened, with only a small risk of scarring. An argon-dye laser is used in eye surgery. The color of light produced by the laser can be adjusted with high precision. It can be made to produce light ranging across the green-to-blue color range. Each shade of green or blue has a slightly different frequency. It can penetrate more or less deeply in the eye. The laser can be adjusted to treat a very specific part of the eye. The argon dye is used to treat tumors, damaged blood vessels, conditions involving the retina, and other kinds of eye problems.
What is one use of argon?
Argon is used to make argon
What is argon name?
Curiously enough, the name of argon Is argon.
What are the uses of argon?
what are the uses of argon?
What does a gas laser need to work?
I belive one type is an argon laser.
What type of laser is used to correct vision problems?
I believe it is the argon laser.
How is a laser iridectomy done?
To perform a laser iridotomy, the ophthalmologist uses a laser, usually an argon or an Nd:YAG laser, to burn a small hole into the iris to relieve fluid pressure behind the iris. If the procedure is an iridectomy, the laser is used to remove.
What is semiconductor laser?
A semiconductor laser is a type of laser which utilizes a semiconductor as its Photon source, rather than a gas (Argon, CO2, Etc...) laser which uses inert gas as an active medium. Many physicists and engineers consider a semiconductor laser a type of "Solid-State" or "Two-State" LASER.
What is the use of green laser in opthalmology?
I believe you are referring to the Argon Green laser? It's principal uses in ophthalmology are in retinal photocoagulation for vitreoretinal surgeries and diabetic retinopathy.
What does laser iridotomy treat?
Laser peripheral iridotomy makes an opening in the iris allowing the fluid to drain, argon laser trabeculoplasty is aimed at the fluid channel opening to help the drainage system function.
Interesting info about argon?
1. Argon is the third most common gas in the atmosphere (0.90%), more common than carbon dioxide. 2. Argon makes a distinctive blue-green gas laser. 3. Argon is the best choice to extinguish fires when nearby equipment cannot be damaged.
Where could you find argon on earth?
In the Earth's atmosphere. 0.7 % of the atmosphere consists of Argon. In products, in can be found in light sources. It is also used in laser eye surgery, and to grow pure semiconductive crystals.
A helium neon laser emits light of wavelength 633 nm Light from an argon laser has a wavelength of 515 nm Which laser emits the higher frequency light?
according to the wave theory of light,we have the relation that wavelength is inversely proportional to the frequency,therefore the electromagnetic wave with the lower wavelength will have higher frequency..
What has the author Harlan V Wallace written?
Harlan V. Wallace has written: 'Optical characteristics of LEXEL 85 argon ion laser and Gsanger LM0202P modulator'
What is photocoagulation therapy?
Photocoagulation therapy is a method of treating detachments (tears) of the retina (the layer of light-sensitive cells at the back of the eye) with an argon laser. The high-intensity beam of light from the laser is converted into heat.
What are the kinds of laser?
gas lasers: helium-neon, argon, carbon dioxide, nitrogen, etc.liquid lasers: dye, chemical reaction lasers, etc.solid lasers: ruby, semiconductor laser diodes, etc.Lasers can be made many ways. Too many for me to list here.
