How does laser speed guns use lasers?
Laser speed guns use lasers by Doppler shift measurement.
Why optical pumping cannot be used for helium neon laser?
Ans. Optical pumping methods are very ineffective for gas lasers because gas atomsshow sharp energy, levels as compared to solids, which are characterized by energy bands raTher than energy levels. Thus for gas laser the electrical discharge is used for pumping.
What radiation is used in a laser?
Gas Lasers is a kind of laser that sets free electric current over gas to carry out consistent light. Gas Lasers needs to have very high laser beams with extended coherence length.
Laser beam needs electricity or not?
All lasers require electricity to operate. The laser beam that results from operation of a laser is electromagnetic radidation, not electricity.
What two gases combine to form a laser?
An example is the helium-neon laser.
How is he-ne laser superior to ruby laser?
Helium neon laser is better than ruby laser or most of the four level lasers are better than three level lasers due to the following reasons: The laser output is continuous in the case of helium-neon laser. But it is in the form of pulse in the ruby laser. Ruby laser requires high power pumping source, whereas Helium-neon laser requires low power pumping source like electric discharge. Efficiency of helium-neon laser is more than ruby laser. The defects due to crystalline imperfections are also present in the ruby laser. But it is not so in the helium-neon laser.
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.
What is CO2 laser?
It's a gas-tube laser in which the lasing tube is charged with a gas mixture containing about 20 percent carbon dioxide, with some nitrogen, hydrogen and helium mixed in. These are very powerful industrial lasers that operate in the infrared frequency range, and are used for cutting.
What does the military abbreviation peq stand for?
Not sure what the letters actually stand for but PEQ is a portable laser/laser combination. PAQ is an infrared illuminator or aiming light.
What are some of the risks associated with the infra red lasers?
The correct and safe use of an infrared laser pose no health risks. However, there is some danger if a class 3 or class 4 infrared laser is pointed at a human eye.
What is significant about an IR laser?
Infrared lasers are dangerous to the human eye, because it is extremely bright. Infrared lights are invisible and keeps the body from using it's "blink reflex".
Can laser be used in plural as in lasers?
the plural of laser is lasers. for example I have many lasers. you don't say I have many laser.
What are the different kinds of lasers?
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.

What property of light does a laser show clearly?
now lasers can produce many different colors, as well as well as infrared and ultraviolet radiation.
What are Three types of Lasers?
Gas,solid state,diode The first laser was a solid state laser. Solid state refers to any solid material like a glass rod. Diode lasers are very common because they are used to read compact disks and digital video disks in computers, CD players, and DVD players. Before diode lasers, the most common type of laser may have been the helium-neon laser, in which the active medium is a combination of the two gasses helium and neon.
How does a laser cutter work?
Lasers used for cutting are rarely found outside of industrial use, as they are extremely dangerous and very large. Laser cutting is done by CO2 lasers or neodymium lasers. CO2 lasers function by energizing a gas mixture of carbon, nitrogen, hydrogen and helium. Neodymium lasers function in the same way as CO2 lasers, except instead of using gas as the medium, they use a crystal with small amounts of neodymium in it.
