The number of laser types is as many as its uses and the fields of medicines where it can be used. Technological advances have allowed man to endlessly find ways on how a laser can be used. So now, lasers are used in a number of ways to solve a variety of problems.
Laser types actually differ from one medical field to another. Those being used in laser eye surgery may not be applicable to those who will need it to treat cancer types.
There are, however, four laser types that are commonly used in medical treatments. Each is differentiated by the color of their light beam.
One of this is the carbon dioxide (CO2) laser. It is a surgical tool that converges light energy to heat. It is so strong that bleeding is minimized while the laser beam vaporizes tissues. Most of the time CO2 laser is used to treat skin disorders, infected wounds, warts and scar tissues.
Another common type of laser is the neodymium: yttrium-aluminum-garnet (Nd: YAG) laser. This type of laser is like an argon laser because it is absorbed by the pigment. The difference is that the Nd: YAG laser can penetrate deeper into a person's tissue. It also allows blood to clot quickly so surgeons can work on body parts that can only be reached if you go for an open surgery. The Nd: YAG laser can be used to remove tattoos and other pigmented lesions.
A pulsed dye laser is used to treat various cancers. It is considered effective because the beam emitted from this type of laser destroys abnormal tissue without necessarily injuring the surrounding tissues. This is best for children.
The last common type of laser is the argon laser. This is commonly used in eye surgery and superficial skin disorders due to its limited penetration. This is also the only type of laser that can be paired with a light-sensitive dye to dissolve or shrink tumors and certain types of cancers.
Throughout the years, however, more types of lasers have evolved. Some are being used to treat varicose veins, make stretch marks less visible and remove unwanted hair.
