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....

Are there any lasers that can cut through metal?
Absolutely. There are many lasers used in industry for metal cutting. CO2 lasers are the most common, but there are many other types.
What is the difference between cold and hot lasers?
Cold lasers are safer and deal less pain than hot lasers. Cold lasers are usually used for repairing skin damage and treating pain and inflammation. Hot lasers are simply used for burning things.
Are all lasers dangerous because they are hot?
no not all lasers are really
Where can one purchase lasers of different wavelengths?
Lasers of different wavelengths can be purchased from many sites online, such as Lexel Laser, and Wicked Lasers. Be sure to check the legality of the lasers in your country or risk losing them at customs.
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.
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.

Why electrical pumping is using for gas laser?
gas lasers do not usually lend themselves to lamp pumping because the absorption lines are typically much narrower than the usual broadband emission of the lamp. Electrical pumping of gas lasers ,on the other hand can be a fairly efficient process because the linewidth of excitation cross section of a given transition by electron impact is usually quite large

What can be used for different types of surgery.?
its not lasers are Diffractions it is refractions
What type of lasers does Erchonia manufacture?
Since the early 1970s Erchonia lasers have been classified by wavelength and maximum output powers into four classes. The lasers are used in treatment of neck and shoulder pain, breast augmentation, acne, laser assisted body augmentation. The types of lasers they use for these treatments include 3LT Lasers, Custom Design Lasers and Zerona Lasers.

How can lasers be used to treat wrinkles?
Lasers can be used to treat wrinkles by a laser resurfacing procedure. It can be done with two types of lasers: one that removes thin layers of skin and the other type that stimulates collagen growth.
What Types of tissues is responsible for pumping blood throughout the body?
The cardiac muscle of the heart has primary responsibility for pumping blood throughout the body.
Can you use any type of crystal in in a laser?
No; only some types of crystals, gases, etc. can be used in lasers.
What are the different types of tuning in tunable laser?
Tunable lasers can be tuned in various manners. Some of these include single line and multi line tuning. Narrow band tuning is also used to tune various lasers as well.
