Laser Therapy 101

Useful Information

If you are new to laser therapy, you will find the following information useful.

LASER

Stands for Light Amplification by the Stimulation of Emitted Radiation

Laser Diode

  • Used to produce the laser beam either Visible Red (eg 635nm, 660nm) or Infrared (785nm, 808nm, 830nm, 904nm).
  • The VetLaser 3000 comes with a GaAlAs (Gallium Aluminium Arsenide) diode laser.
  • Beware of manufacturers who include LEDs (Light Emitting Diodes) in their systems and then claim them as being ‘laser therapy’ units.

Laser Diodes have been proven to penetrate deeper into muscle tissue than LEDs!

An excellent article about laser diodes can be found on Wikipedia.

Penetration Depths

  • Visible Red lasers penetrate around 15mm into the tissue. These are perfect for treating Acupuncture & Trigger points as well as wounds and scars that are close to the animal’s body
  • Infrared lasers penetrate 50mm into muscle tissue and are ideal or treating large muscle groups as found on dogs and horses

Frequency

  • Continuous Wave – the laser beam is constantly on during operation
  • Pulsed Nogier frequency – the laser is momentarily switched off during the treatment session and then switched back on.
  • The VetLaser 3000 comes with 7 pulsed Nogier frequencies from 73Hz-4672Hz.

The following link has information about Nogier Frequencies.

Joules

  • Energy delivered by the laser per treatment session, measured as J/cm2.  It is possible to manually enter the dosage required in the VetLaser 3000, the unit then calculates the time taken to deliver the dosage.
