Alternative Treatments With Cold Lasers

Have you heard about the use of cold lasers to cure countless diseases? Cold lasers are being used by doctors, dentists, acupuncturists, DOs, oral surgeons, veterinarians, chiropractors, and the list goes on. Treatment with cold laser therapy is becoming one of the fastest-growing areas of alternative medicine.

The first cold laser light therapy was used 30 years ago. Cold lasers have been used routinely for nearly 20 years in Europe, Asia, and Canada, and yet in the US, they are relatively new to mainstream medicine. Why is it like this? Just 3 years ago the United States FDA began approving cold lasers for use in specific areas.

Additional names that are often used interchangeably with cold lasers are low-level laser (LLT), photobiostimulation laser, photobiomodulation laser, biostimulation laser, regulating laser, soliton laser, and soft laser. Until a consensus is reached, the two most important names to remember are cold laser and low-level laser, which are often used interchangeably with low-level laser therapy (LLLT).

Why is it called a cold laser? A laser that uses a diode of 500 mW or less is called a cold laser because it does not produce enough heat to heat the treated tissue. Different types of cold lasers are available in the market with different power outputs and different wavelengths. Common diode power outputs include: 5 mW, 30 mW, 50 mW, 100 mW, 200 mW and 500 mW. The higher the power output, the shorter the treatment usually.

Is there a difference between a laser and an LED? Yes, this is an important difference, which comes down to consistency and depth of penetration. A cold laser uses coherent, polarized light that is highly focused and pillared, allowing it to travel long distances in a straight line or penetrate the deeper layers of the body. LED's light is monochromatic, non-coherent light, useful for the treatment of superficial tissues such as wounds and skin conditions.
