Terraquant Cold Laser Compare

Our goal at ColdLasers.Org is to sell the best cold lasers and to present unbiased information about cold laser therapies. In addition to being the fastest growing TerraQuant cold laser and MedX low level laser source, this site includes information about different cold laser technologies and different style of cold laser therapy. The most accepted uses for cold lasers are damaged tissue healing, inflammation reduction and pain reduction treatment. In addition to these treatments, Cold Lasers are used for dental surgery, hair growth, stop-smoking therapy and many other applications. This site will review each type of therapy and discuss treatment options and possibilities. In addition, this site will review the different types of lasers and the specifications of different lasers (including Terraquant, Apollo, Scalar Wave, Erchonia, VetroLaser, K-Laser and Microlight ML830). Comparing cold laser can be a challenge since every manufacturer used different wavelengths, power levels, emitter technologies and treatment systems.

Cold laser light is:

  • Monochromatic (A single wavelength in the 635 to 970 nm range)
  • Coherent (Traveling in a straight non-diverging line)
  • Has a wavelength in red portion of the electromagnetic spectrum
  • Polarized (Concentrating it energy as a defined spot)
  • Low power level ranging from 10 continuous to 50,000 pulsed milliwatts (Cold)

Unlike high-power medical laser, which are widely used to safety cut and burn tissue, the Low Level Laser (LLL) or cold laser penetrates the surface of the skin with no heating effect or damage. The energy is directed deep into effected area stimulating the body’s cellsl which convert the energy into chemical energy to promote natural healing.

In most cases, Cold Laser Therapy is considered an alternative therapy like Acupuncture and physical therapy because it does not require expensive surgeries or a life-long dependency on drugs. Cold Lasers user laser energy to help the body heal itself. Traditional medicine practitioners sometimes favor treatment options like Ultrasound And Tens. These treatment have provided relief for many patients over the years and may be used in combination with cold laser treatment for even better results.

Currently, there are over 25 different cold lasers or LLLs that have been cleared by the FDA for various types of treatments. Cold laser have been in use around the world for over 30 years and have been in use in the US for over 10 years, mostly in the veterinary field. Low level laser therapy or soft laser therapy has been proven completely safe in over 3000 worldwide studies.

The power level of medical grade cold lasers ranges from 10 milliwatts to 50,000 milliwatts. The higher power level are only available for laser with pulse technology. This energy can be created using one or an array of laser sources. An array of lasers allows a wider treatment area. Since finding the optimum treatment spot deep inside the tissue is somewhat of an "educated guess", it can be very useful to cover a larger area with an array. This increased the probability of getting the photons to the problem area and larger arrays also also help increase the energy in the area surrounding the main target area. Emitters that use a combination of different wavelength source also have a better chance of treating tissue at different depths.

The average cold laser therapy session cost from 30 to 60 dollars. The average medical grade laser costs from $4000 - $15,000. Because cold lasers increase blood flow in the treated area and activate the bodies natural healing processes, they are typically used for:

  • Cervical (neck pain) healing
  • Lumbar (low back pain) healing
  • Wrist pain and injuries
  • Elbow and joint pain and injuries
  • Lower extremities pain
  • Foot and ankle pain
  • Knee and joint pain and injuries
  • Treatment after dental surgery

There are 2 basic styles for treatment using cold lasers, pinpoint treatments and broad coverage of a damaged area. Each treatment style has a different goal that requires different equipment.

Laser Puncture Therapy

In a Laser Puncture treatment, the cold laser is used similar to acupuncture or acupressure to trigger a reaction from the body by stimulating an acupoint. In this case, a probe set or focused low level laser is used to concentrate all the energy from the cold laser into a very small area. Cold lasers are often compared to "acupuncture with a laser beams". In LLL LaserPunctur treatments, the laser beam is use to stimulate the body's acupoints or damaged areas in an attempt to increase the blood supply to parts of the body. The energy from the laser may penetrate as deep as 5 inches into the body based on the power of the laser and other variables.

Broad Treatment Therapy

Another common low level laser treatment is based on using a cold laser with a broad focus and the correct wavelength to penetrate the deep tissue with photons to accelerate natural healing in a large area. These large emitter can cover areas up to 4.6 inches. The larger treatment area increase the chances of stimulating the hotspots that need healing the most. Larger Emitters also reduce the treatment time.

Some other common names for cold lasers are low level lasers or soft lasers. In some publications, you may see the abbreviation LLLT for Low Level Laser Therapy. Click on the links on the left toolbar to see more information about the different cold lasers and cold laser therapy options.

Cold Laser Comparisons

The 3 key factors for comparing cold lasers are:

  • Wavelength - The wavelength controls the depth of the penetration of the laser photons.
  • Power - Since the power of a laser usually remains constant during a treatment, the energy of the light is equal to the power in watts multiplied by the time in seconds during which the light is emitted. For a continuous laser, this is simply watts times time. For a pulsed laser, the calculation is watts x duty cycle x treatment time. A laser with more power (measured in watts) or a higher duty cycle (measured in max duty cycle) can deliver the more energy (measured in joules) in less time. Joules is the best way to compare pulsed and non-pulsed laser for their ability to direct energy into the deep tissue and initiate healing.
  • Coverage Area - The larger the coverage area, the faster the treatment.

At the most basic level, cold lasers use a variety of different treatment plans to stimulate natural healing. The goal of cold laser therapy is to deliver light energy units (in photons) to damaged cells. Photons are absorbed by the cells and stimulate the mitochondria to accelerate production of ATP. An ATP increase in cell energy helps accelerate the bodies healing process by transforming cells from a state of damage to a stable, healthy state.
