Laser therapy is the medical use of concentrated, coherent light to treat disease, modify tissue, or promote healing, exploiting the precise control of wavelength, power, and exposure that lasers afford. It spans a spectrum from high-power applications that cut, ablate, or coagulate tissue to low-level approaches, also termed photobiomodulation, that deliver light at intensities intended to stimulate cellular activity rather than destroy tissue. Low-level laser therapy is investigated for its capacity to reduce inflammation and pain and to accelerate repair, as in adjunctive periodontal treatment that lowers inflammatory markers, the enhancement of bone remodelling and pain control in fractures, and effects on reparative osteogenesis, while photobiomodulation is also examined in relation to mood and cognition. Higher-energy and fractional laser techniques are used in dermatology and surgery, exemplified by fractionated erbium:YAG laser skin microporation combined with topical agents for premalignant and malignant skin lesions, and by photocoagulation in ophthalmology. The therapeutic effect depends on matching wavelength and dose to the target tissue and chromophore. Significance lies in offering precise, often minimally invasive intervention across multiple specialties. Principal sub-areas include low-level laser therapy and photobiomodulation, ablative and fractional laser treatment, laser photocoagulation, and the dosimetry and tissue-interaction principles that govern safe and effective application.
