Table 1 Low-level laser therapy parameters

From: Effect of low-level laser therapy on the expression of inflammatory mediators and on neutrophils and macrophages in acute joint inflammation

Group λ(nm) Type of diode laser Mean power output (mW) Spot size (cm2) Power density (W cm2) Energy (J) Energy density (J cm2) Time per point (seconds)
50 mW LLLT 808 GaAlAs 50 0.028 1.78 4 142.4 80
100 mW LLLT 808 GaAlAs 100 0.028 3.57 4 142.4 40
  1. GaAlAs - arsenide and aluminum gallium; λ, - wavelength; LLLT - low-level laser therapy.
