COMMON TERMS
Applicator – Hand held assembly that delivers Laser
energy and includes laser head, diode, and related
electronics
Collimating – The shape of the Laser beam. It is neither
focused or dispersed and resembles a column when
applied
Continuous Mode – The output of the Laser is not
interrupted during the treatment time
Dosage – Intensity measurement of the Laser energy over
the treatment area. It is measured in Joules or Joules/cm 2
Energy – Measured in Joules, energy equals the treatment
time multiplied by the power. Energy density equals the
power output multiplied by the treatment time, and
divided by the spot size (cm
2 ). This gives a more specifi c
measurement of energy delivered
Frequency – Pulsed frequencies are selectable from 8 to
10,000 Hz
Laser Head – The clear lens applicator face 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 treatment time and penetration of the
Laser energy. High-powered diodes will reduce patients’
treatment times 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
Pulsed Mode - This is the ratio of the “On” time to the
“Total” time of the cycle, expressed as a percentage.
The lower the percentage, the lower temporal average
intensity. 100% is continuous Laser. Pulsed Mode is 90%
on and 10% off
NOTE: Pulsed Mode is also equivalent to Duty Cycle.
Spot Size - Area of the LED, SLD, or laser beam when it
leaves the face of the lens
Treatment Area - Area of tissue aff ected by LED, SLD, or
laser when wavelength, divergence angles, and depth of
penetration are factored. This is the area used to calculate
dosage
Treatment Time – Measured in seconds, it is the
suggested time per laser point that therapy is given
Wavelength – Wavelength is measured in nanometers
(nm) and is the key component in obtaining eff ective
therapy as diff erent wavelengths cause diff erent
physiological eff ects. Superfi cial skin disorders are most
eff ectively treated at wavelengths 600-700 nm, while
deeper muscular or ligament lesions and joint conditions
are best treated at higher wavelengths of 700-1000 nm.
