What are Gas Lasers?
Gas lasers are a type of laser that uses a gas mixture as the laser medium to produce coherent light. The gas mixture is typically excited by an electrical discharge or other means to generate the laser beam. Gas lasers are used in various applications such as cutting, marking, welding, and scientific research.
What is the difference between lasers and tunable lasers?
All tunable LASERs are LASERS, however not all LASERS are tunable. In a tunable laser the lasing medium, which is typically a gas, dye or crystal, can be altered to produce slightly different frequencies, thus allowing the laser to be 'tuned' or frequency changed where most LASERS produce a very narrow band of radiation frequencies.
What parts do lasers have?
Lasers typically have three main components: a gain medium (such as a crystal or gas) that amplifies light, an energy source (such as a pump source) to provide the necessary energy for the gain medium to amplify light, and optical cavity or resonator to reflect and amplify the light in a coherent manner.
What are the types of pumping in lasers?
A laser emits a beam of energy in the form of light. But to get energy out of a laser, we have to put some in. Depending on the type of laser, there are different ways to do this. What is important here is that the energy put into the lasing medium, the energy that is pumped into that medium to stimulate it, to excite it (the actual term), to induce it to lase, is supplied by an outside source, by a pump appropriate to that type of laser. So the pump, that thing outside the medium that stimulates it to induce it into lasing, is pumping when it is exciting the medium. Hope this was, um, coherent....
Why is only one colour produced in a Laser Beam?
The color of a laser beam is determined by the type of material used in the laser, such as a specific gas or semiconductor. These materials emit light at a specific wavelength, resulting in a single-color beam. Additional optics can be used to combine different lasers to produce multiple colors in laser light shows.
What are the different kinds of lasers?

What common items contain argon?
Argon can be found in fluorescent light bulbs, lasers, and some welding applications. It is also used in the production of semiconductor materials and as a gas for protecting materials from oxidation during manufacturing processes.
What noble gas makes lasers?
All noble gases - He, Ne, Ar, Kr, Xe - were used in lasers.

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 laser has the most power output solid state or gas?
Solid-state lasers typically have higher power output compared to gas lasers. This is because solid-state lasers can efficiently convert electrical power into laser light, resulting in higher power outputs. Gas lasers, on the other hand, tend to have limitations in power scaling due to factors like gas flow and cooling.
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.
