The first laser was built in 1960 by Theodore H. Maiman at Hughes Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light coherently.
Cold laser therapy is a relatively new technology compared to many alternative therapies like acupuncture (which has been used since 8000-3500 B.C.), chiropractic (since 1895) and physical therapy. Just like the abacus evolved into the computer, many alternative medicine practices are evolving to include laser therapy. Recent innovations in low-level lasers now make it possible for practitioners or consumers to own high quality cold laser equipment. The first cold laser was FDA cleared in 2001.
