ABOUT LASER LIGHT THERAPY
Applicator
- The hand held assembly used to deliver laser energy. The applicator includes the laser head, diode, and related
electronics.
Collimating
- The shape of the laser light beam. While neither focused nor dispersed, this laser light beam resembles a column when
applied from the unit through the applicator.
Continuous Mode
– The output of the laser is not interrupted during the treatment time.
Dosage
– A measure of the intensity of the laser light energy over the treatment area. The unit of measure is Joules or Joules/cm
2
.
Energy
– Measured in Joules, energy equals the treatment time multiplied by the power. More importantly, Energy Density equals
the power output multiplied by the treatment time, and divided by the spot size (cm
2
). This gives a more specific measurement of
energy delivered.
Frequency
– Pulsed frequencies are selectable from 8 to 10,000 Hz.
Laser Head
– The clear lens face of the applicator that contacts the patient’s skin. It consists of laser diodes with or without LED’s or
SLD’s (depending on the applicator).
Power
– Measured in Watts (W), power wattage is directly proportional to the treatment time and penetration of the laser energy.
High-powered diodes will reduce patients’ treatment time and give a higher amount of energy at a deeper depth. Power output
can be either continuous or pulsed.
Power Density -
Ratio of power divided by treatment time.
