The use of laser technology in gynaecology

The use of laser technology in gynaecology has become widespread from the early 1970’s by the introduction of CO2 lasers for the treatment of cervical erosions and other colposcopy applications. Since then, many advancements in laser technology have been made, and several other types of lasers are now available, including the latest semiconductor diode lasers.

How deep into the tissue can laser light penetrate?

How deep into the tissue can laser light penetrate?

The level of tissue penetration by the laser beam depends on its optical characteristics, as well as on the concentration and depth of the chromophores, which according to the wavelength are absorbed at different percentages. For instance, water absorbs almost 100 percent of the laser irradiation at the 10,600 nanometer wavelength, the wavelength of the CO2 gas laser. That is the reason why this type of laser wavelength is used in surgical applications.

Other factors affecting the depth of penetration are the technical design of the laser device and the treatment technique used. There is no exact limit with respect to the penetration of the light. The laser light gets weaker the further from the surface it penetrates with a limit at which the light intensity is so low that no biological effect of the light can be measured. In addition to the factors mentioned above, the depth of penetration is also contingent on tissue type, pigmentation and foreign substances on the skin surface. Bone, muscles and other soft tissues are transparent to certain laser lights, which means that laser light can safely penetrate these tissues.

The radiation in the visible spectrum, that between 400 and 600 nanometers, is absorbed by the melanin, while the whole extension of the visible which goes from 420 to 750 nanometers is absorbed by composite tetrapyrrolics. In the infrared, which covers about 10,000 nanometers of the light spectrum, water is the main chromophore. Fortunately, there exists a narrow band in the light spectrum where water is not a highly efficient chromophore, thereby allowing light energy to penetrate tissue that is rich in water content. This narrow band, which extends approximately from 600 to 1,200 nanometers, is the so-called therapeutic window. That is the reason why the therapeutic lasers in the market today have wavelengths within this therapeutic window. The penetration index is not the same level throughout the therapeutic window. In fact, lasers in the 600 to 730 nanometers have less penetration and are suitable for superficial applications such as in acupuncture.

The difference between LED therapy and Laser therapy

The difference between LED therapy and Laser therapy

Light emitting diodes (LED) are just tiny light bulbs that fit easily into an electrical circuit. But unlike ordinary incandescent bulbs, they do not have a filament that will burn out. They are illuminated solely by the movement of electrons in a semiconductor material. LED’s produce incoherent light just like an ordinary light bulb does. Light from LED’s have very little tissue penetration compared to laser light.

By applying the first law of photochemistry (Grotthus-Draper Law), which states that light must be absorbed by a molecule before photochemistry can occur, one can immediately conclude that light from LED’s would work only on skin level conditions, if at all. For conditions deeper than skin layers one must choose light from a laser source.

What is laser therapy?

What is laser therapy?

For a long time now L.A.S.E.R. (Light Amplification by Stimulated Emission of Radiation) was an acronym and today a word of common use. The word LASER is the name of a device that projects intense radiation of the light spectrum. It produces a beam of light in which high energies can be concentrated.

Laser light has unique physical properties, which no ordinary light has. The unique properties of coherence and monochromaticity are the key to why laser light is so effective compared to other kinds of light in pain reduction and healing.

Laser therapy, also known as phototherapy and low level laser therapy, involves the application of low power coherent light to injuries and lesions to stimulate healing and reduce pain. It is used to increase the speed, quality and strength of tissue repair, resolve inflammation and give pain relief. Laser therapy has been found to offer superior healing and pain relieving effects compared to other electrotherapeutic modalities such as ultrasound, especially in chronic problems and in the early stages of acute injuries. Laser therapy is a complete system of treating muscle, tendon, ligament, connective tissue, bone, nerve, and dermal tissues in a non-invasive, drug-free modality
