How does laser light work?
In medicine, lasers allow surgeons to work at high levels of precision by focusing on a small area, damaging less of the surrounding tissue.
What is laser therapy?
Laser therapies are medical treatments that use focused light. Unlike most light sources, light from a laser (which stands for l ight a mplification by s timulated e mission of r adiation) is tuned to specific wavelengths. This allows it to be focused into powerful beams. Laser light is so intense that it can be used to shape diamonds or cut steel.

What type of surgery uses special light beams instead of instruments for surgical procedures?
Laser surgery is a type of surgery that uses special light beams instead of instruments for surgical procedures.
What part of the skin absorbs light?
Each layer of the skin uses the light differently. Certain parts of the skin, called chromophones, absorb the light. When these chromophones absorb the light, physical, mechanical, chemical, or temperature changes may occur in the tissue.
How do lasers work?
A laser is created when the electrons in atoms in special glasses, crystals, or gases absorb energy from an electrical current or another laser and become “excited.”. The excited electrons move from a lower-energy orbit to a higher-energy orbit ...
What type of lasers emit light?
Some lasers, such as ruby lasers, emit short pulses of light. Others, like helium–neon gas lasers or liquid dye lasers, emit light that is continuous. NIF, like the ruby laser, emits pulses of light lasting only billionths of a second. Laser light does not need to be visible.
How do mirrors work in glass?
Mirrors at both ends of the glass amplifier cause the photons to travel back and forth through the glass, stimulating more electrons to drop to their lower energy states and emit photons. This process produces huge numbers of photons of the same wavelength and direction—an extremely bright and straight beam of light.
How many wavelengths does laser light have?
First, its light contains only one wavelength (one specific color). The particular wavelength of light is determined by the amount of energy released when the excited electron drops to a lower orbit. Second, laser light is directional.
How much power does a laser have?
Modern lasers can produce pulses that are billions of times more powerful. Scientists have demonstrated NIF’s ability to generate more than 500 trillion watts of power. Some lasers, such as ruby lasers, emit short pulses of light.
How long does a flash of light last in NIF?
In NIF, as in most large lasers, intense flashes of white light from giant flashlamps “pump” electrons in large slabs of laser glass to a higher-energy state that lasts only about one-millionth of a second.
Is laser light coherent?
These photons are all at the same wavelength and are “coherent,” meaning the crests and troughs of the light waves are all in lockstep. In contrast, ordinary visible light comprises multiple wavelengths and is not coherent. Laser light is different from normal light in other ways as well.
What is laser therapy?
Laser therapy is a medical treatment that uses focused light to stimulate a process called photobiomodulation (PBM). During PBM, photons enter the tissue and interact with the cytochrome c complex within mitochondria. This interaction triggers a biological cascade of events that leads to an increase in cellular metabolism, ...
Why are therapeutic lasers so disappointing?
Early therapeutic lasers had very low powers (less than 0.5 W) and very small beam areas (or spot sizes); consequently, early studies were often disappointing because the low powers were not able to provide a sufficient number of photons to significantly impact injured cells.
How does PBM work?
For PBM to occur, light needs to reach the mitochondria of the damaged target tissue. When laser therapy is applied to the surface of the skin the best results are achieved when a sufficient amount of light (number of photons) reaches the target tissue. There are a number of factors that can help maximize the light that reaches the target tissue, ...
How does power affect photobiomodulation?
Power influences photobiomodulation therapy in a number of ways. When energy is imparted to the body, it is measured in Joules. Joules is the product of power (Watts) x time (seconds). By definition, higher power allows Joules to be delivered to tissue in less time.
What is photobiomodulation therapy?
Photobiomodulation therapy is defined as a form of light therapy that utilizes non-ionizing light sources, including lasers, light emitting diodes, and/or broadband light, ...
What is the energy that is absorbed by melanin?
Energy that is absorbed by melanin or water in the body is energy that is lost at the target tissue.
What is the class of laser?
These classes include IIa (bar code scanner), IIIa (laser pointer), IIIb (industrial and therapy lasers <499 mW), and Class IV (all lasers >500 mW). In December 2003, the FDA approved the first Class IV laser for the relief of minor muscle and joint pain.
