What Is Laser Therapy

What Is K-Laser Therapy?


Laser Therapy is the use of a laser light to deliver specific red and near-infrared wavelengths to parts of the body in order to induce a photo-chemical reaction and therapeutic effects.

Therapy lasers are sometimes also called "Cold Laser" or "Low Level Laser". The most powerful lasers are classified as Class iv lasers (power >500mW). K-Laser units being over 15W are often referred to as HILT (High Intensity Laser Therapy).

Laser therapy has been used in Europe since the 1970s and was cleared by the United States Food and Drug Administration (FDA) in 2005. Class iv Laser Therapy is very common in Europe and USA.

Main Physiological Effects Of Laser Therapy

  • Increase Blood Circulation
  • Reduce Inflammation
  • Reduce Pain
  • Enhance Tissue Healing

Cellular Effects

During K-Laser Therapy, infrared laser light interacts with tissues at the cellular level increasing metabolic activity within the cell. By improving the transport of nutrients across the cell membrane, the increased production of cellular energy (ATP) is stimulated. The cascade of beneficial effects that follows includes increased cellular function and tissue repair.

The way Laser Therapy Works

During each painless treatment, laser energy increases circulation, drawing water, oxygen, and nutrients to the damaged area.

The K-Laser therapy session creates an optimal healing environment which reduces inflammation, swelling, muscle spasms, stiffness, and pain. As the injured area returns to normal, function is restored and pain is relieved.

K-Laser Frequencies

There is always some debate as to which are the “right” parameters for which conditions. Tissues absorb light, and more specifically, the photon absorbing chromophore. K-Laser employs the broadest range of wavelengths and frequencies to target each relevant tissue type. Each step in the bio-modulation mechanism, within every treatment, will have the greatest chance of enhancing all healing processes involved.
Different pulse frequencies elicit different physiological responses. During laser therapy, it is beneficial to deliver a variety of pulse frequencies. K-Laser has taken everything known about the makeup of each anatomical part and modified the settings to target just the right amount of bone, soft tissue, and fat.

K-Laser’s approach uses the largest variety of laser parameters utilising multiple distinct phases within each protocol. This dynamic range, combining 4 wavelengths and frequencies from CW (Continuous Wavelength) to 20,000 Hz (Pulse frequencies), has the best chance at stimulating all of the body’s cells to heal themselves more efficiently.

K-Laser Wavelengths

Wavelengths determine laser energy’s depth of penetration in tissue and target selected beneficial chromophores to stimulate the photo-chemical reaction. K-Laser is the only laser providing 4 different wavelengths (660nm, 800nm, 905nm, 970nm) targeting the body’s four natural light absorbing complexes:
  • Melanin
  • Cytochromes
  • Haemoglobin
  • Water


Irradiating an area with 660nm, a wavelength where melanin in our skin absorbs very well, will ensure a large dose to the superficial region. Since light can both inhibit bacteria and promote cell growth, laser therapy has incredible results in wound healing and scar tissue regulation.


The enzyme determining how efficiently the cell converts molecular oxygen into ATP has the highest absorption at 800nm. Regardless of the enzyme’s molecular state, when it absorbs a photon it will flip states. Photon absorption will accelerate the process and increase cellular ATP production.


The quicker oxygen is released into the blood stream, the more fuel the cell has to carry out all of its natural healing processes. The peak of haemoglobin's absorption lies at 905nm, and when this radiation is absorbed, more of this oxygen-fuel is made available to the cells.


Water in blood transports oxygen to the cells, carries waste away, and absorbs very well at 970nm. The energy created from absorbing a photon gets converted into heat, creating a temperature gradient at the cellular level, stimulating micro-circulation, and bringing more oxygen-fuel to the cells.
