What Is Laser Therapy?

What is Veterinary Laser Therapy?

Veterinary 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 photochemical reaction and therapeutic effects.

Therapy lasers are sometimes also called "Cold Laser", "Low Level Laser" and are classified as Class iv lasers.

Laser therapy has been used in Europe since the 1970s and was cleared by the United States Food and Drug Administration (FDA) in 2005.

Main Physiological Effects Of Laser Therapy:

Increase Blood Circulation

Reduce Inflammation

Reduce Pain

Enhance Tissue Healing

How Does K-Laser Therapy Work?

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.

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.

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 utilizing multiple distinct phases within each protocol. This dynamic range, combining 4 wavelengths and frequencies from CW (Continuous Wavelenght) 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 applications on pets are exactly the same than applications on humans and will offer amazing results.




The Mechanism

K-Laser Wavelengths

Wavelengths determine laser energy’s depth of penetration in tissue and specifically target beneficial chromophores to stimulate the photochemical 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
  • Hemoglobin
  • 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 hemoglobin’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 microcirculation, and bringing more oxygen-fuel to the cells.

K-Lasers are Powerful

Wavelength determines a laser energy’s depth of penetration.
Power determines it's saturation at the targeted depth.

One goes with the other.

Power (Watts) is the number of photons of radiation you can deliver per unit time. The energy deposited (Joules) is the accumulation of these photons over time (1 Watt=1 Joule per 1 second). By starting out with more Watts at the surface, more will penetrate to desired depth.

For an illustration, consider the following:
​1 Watt laser: 40 seconds to deliver 10 Joules of energy to a 4 cm depth
​4 Watt laser: 10 seconds to deliver 10 Joules of energy to a 4cm depth

The higher-powered laser will be able to deliver therapeutic doses​ to deeper targets in a shorter amount of time.

K-Laser Intense Super Pulse (ISP)

Lasers operating in super pulse mode deliver bursts of high peak power for a short period of time.

The K-Laser Intense Super Pulse (ISP) mode delivers more laser energy to deeper tissues mitigating superficial heat build-up. The unique, and K-Laser exclusive, highpowered 20W ISP mode lets the laser operator choose the proper power output and pulse frequency for effective laser therapy.
