Wavelength is one of the most critical factors when it comes to the efficacy of laser therapy.  Varying wavelengths exhibit a variety of therapeutic effects depending where they fall on the spectrum, and, in some cases, no therapeutic effect at all!

Respond Systems has conducted years of research in the lab and in the field and uses proven wavelengths to achieve the following effects on the cellular level:

• 670nm visible red light: optimal efficacy for wound healing and dermatology.
• 808nm near infrared light: ideal for surface conditions and those just under the surface of the skin.
• 904nm near infrared light: maximum depth of penetration to reach the conditions deeper inside the body.

Two types of laser diodes are commonly used in laser therapy: continuous wave (CW) laser diodes and what are commonly known as “Super-Pulsed” laser diodes. Both CW and Super-Pulsed laser diodes produce the same beneficial laser light; they just deliver the light to the tissue differently. Continuous diodes deliver a constant and stable power output, ideal for most treatment situations. Super-pulsed laser diodes use very short pulses of laser energy—just fractions of a second—but at very high power (up to 50 Watts) to enhance laser penetration into deep tissue. By turning the laser on for a brief period at very high power, you achieve the benefit of deep penetration without the risk of heating or burning that arises when using higher power, continuous wave diodes for long periods. A recent study of Super Pulsed Laser Penetration found our Respond 904nm Super-Pulsed laser penetrates through more than 6″ of tissue tested, including an equine neck and hock.

All laser devices are classified by the FDA based upon the hazard they present. Class 3b and Class 4 lasers are commonly used for Laser Therapy, with Class 4 being the highest powered and presenting the greatest hazard to the eye, and requiring the most precautions. It is important to note that laser class is only about safety, and has nothing to do with the effectiveness of a device. At Respond Systems, we manufacture both Class 3b and Class 4 lasers providing our customers with clear options to fit their needs.

Class 3b and Class 4 lasers are equally as effective for use in laser therapy as they both emit laser light at a specific wavelength and it is this wavelength that contains the secret to effectiveness. However, high power lasers at the Class 4 level can greatly reduce treatment time due to the power level and we have engineered our Class 4 to multiple horses quickly and safely. Laser Therapy is a stimulus for natural healing and should never burn. By dispersing the power density over a 50sq cm area, we have engineered our Class 4 laser system to deliver high power safely and effectively.

On the flipside, lasers at too low a power level cannot deliver the effective dose of LLLT because the time required to administer the dose is too high or the power is too low to penetrate to a depth to reach the weakened tissue.  Respond System’s lowest level of laser is Class 3b and has the highest power output in that Class to ensure effective dosing.

The vast majority of positive studies over the past 40 years support the benefits of Laser Therapy (LLLT), not LED’s. Many manufacturers of LED systems will cite laser studies in support of their products!

Laser is coherent light which means that the light is composed of spatially coherent waves of identical frequency. The light waves complement each other and enhance the light’s ability to penetrate into the tissue. LED’s do not produce the coherent light and the beam is divergent meaning that the LED light waves can and do interfere with each other preventing the light from penetrating past the surface of the skin.

Energy from LED’s also can cause heat at the surface, which is contraindicated for most acute conditions. By contrast, LLLT stays cool, and can be safely and easily paired with treatments where icing is recommended.

Laser dosage is most precisely delivered in the contact
mode. This is because of two main reasons:

• One, the laser light can scatter and the dosage can be drastically reduced even with a half of centimeter of space between the surface of the area being treated and the lens of the probe. Therefore, to ensure that you are delivering enough joules to have an effective treatment, contact mode is crucial.
• Two, when applying your dose in contact mode, the pressure of the probe on the skin pushes a bit of the fluid in the tissue out of the way to allow for deeper penetration of the laser light.

There is no question from one treatment to the next, that
the patient is receiving the prescribed dosage when treating directly in the
contact mode.

In over 1,800 publications worldwide since the 1960’s, laser therapy has demonstrated its non-invasive, non-toxic quality, and its efficacy in the treatment of acute pain and chronic degenerative conditions, improving the speed and quality of wound healing, and for muscle, tendon and ligament injuries.
