Frequently Asked Questions - Laser Therapy, Photobiomodulation

Q. What is LLLT, LPLT, therapeutic laser, soft laser, MID laser?

Answer: The term LLLT (Low Level Laser Therapy) is generally choosen for cl. 3B. The laser instrument is the term "therapeutic laser" rather than "low level laser" or "low power laser", because cl. 4 at high-level are used for laser therapy as well. The term "soft laser" is an old term.
The energy transferred to tissue is the product of laser output power and treatment time, which is why a "low-energy laser", over a long period of time, can actually emit a large amount of energy. In USA many use the term "cold laser" but in reality there is not cold laser even a single photon generates "heat".
