Overview of MLS Laser Therapy

Laser Therapy Physics

There are many types of medical lasers.  Each laser has different characteristics which result in a different effect.  These characteristics include:

  • MLS Laser TherapyEnergy: measured in joules
  • Time: Defined as the duration of irradiance of target tissue and is measured in seconds.  It is also known as Impulse Duration or called “impulse width”.
  • Wavelength: Penetration depth is directed by the laser emission wavelength and the type of tissue (chromosphores).
  • Frequency: Defined as the number of impulses emitted during the unit of time (1 second) and should reflect the condition treated.
  • Power: the rate at which energy is delivered and is measured in watts.
  • Fluence: Energy Density or Dose
  • Irradiance (Also known as Power Density): Power delivered per unit area
  • Emission Mode: Continuous Wave (CW) or Pulsed Wave (PW)
  • Impulse Duration: Duration of laser emission, also called “impulse width”.

Laser therapy uses light to favor and accelerate the body’s natural healing processes. The laser beam is moved over the skin so that the light energy (photons) penetrates the tissue where it interacts with various molecules (chromophores) that cause different biological effects. It produces a photochemical, photothermal and photomechanical effect.
