Why is it called a cold laser?

Hot lasers are used to cut and burn. Cold lasers are used to heal, get rid of inflammation, treat acupoints and trigger points, boost the immune system, donate energy via photons to cells and tissues and over a 10o other applications.
1 W (Watt) equals 1000 mW (milliwatts). A laser that utilizes a diode that is 500 mW or less is called a cold laser, because it does not produce enough thermal output to heat the tissue being treated. A variety of cold lasers are available on 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, generally the shorter the treatment due to faster delivery of energy measured in joules.

Additional names that are often used interchangeably with cold laser are: low level laser, photobiostimulation laser, photobiomodulation laser , biostimulating laser, bioregulating laser, soliton laser and soft laser. Until a consensus is reached, the three most important names to remember are cold laser, phototherapy, and low level laser, which is often used interchangeably with low level laser therapy (LLLT).

Another breed of cold lasers exist, which used superpulsed technology. These lasers usually utilize the longer 904 or 905 nm wavelength galium arsenide diodes with power of between 14 and 30 Watts. Amazingly they are still rated as class 1 lasers, meaning extremely safe. Superpulsed lasers commonly utilize a microprocessor to pulse the laser beam at 100-200 nanoseconds. What this accomplishes is a deep penetration from 4-7 inches into soft and hard tissues, allowing maximum delivery of photons to target tissue. Superpulsed cold lasers are ideal for treatment of musculoskeletal injuries and repetitive strain injuries.
