LASER TREATMENT PARAMETERS

Energy is the power emitted by Lasers expressed in the unit Watts.

(How fast the beam travels)

Another unit used is the Joules which is derived from Watts x Seconds

(How fast and far the beam travels)

Spot size refers to the size of the beam on the target. With spot size by adjusting this parameter alone can make a difference. The smaller the spot size the intense the energy is under normal settings damage is more with a smaller footprint. Unlike Large spot size, the beam is distributed which makes the energy delivered less intense, results in deeper penetration of the target specially in skin tissue.

Pulse Width also commonly known as

Pulse Duration refer to the length of time the laser emits or time a laser is fired. 

The units can be measured in seconds, milliseconds (ms), micro-seconds (µs), nano-seconds (ns), pico-second (ps)

Shorter pulse widths fast energy delivery on the target results in less absorption and more targeting with minimal damage to surrounding areas. While Longer pulses allows the laser beam to be absorbed by the target for a longer time which can either cause harm or benefit depending on your goal.

Frequency also known as 

"repetition rate"

Unit is in "HERTZ" not the rental car company. Higher frequencies result in continuous heat build up. Lower frequencies allow precise targeting, greater cooling between pulses with better control. 

CONTINUOUS WAVE OR CW

• the laser emits a continuous, uninterrupted beam of light at a constant power output.
• Duration: The laser is on the entire time, with no pulsing or breaks in emission.

• Single Shot mode delivers a single pulse of laser energy, providing a controlled, isolated burst.
• Duration: Each pulse has a defined duration, depending on the laser system’s settings.

• Multi-pulse mode delivers a series of pulses in quick succession, allowing intervals between pulses. The number and frequency of pulses are adjustable, enabling customized energy delivery.
• Duration: Each pulse in the sequence has a defined width and interval, creating a "train" of pulses.

• ULTRA-PULSE Ultra-pulse mode delivers extremely short, high-energy pulses with very high peak power. Each pulse is brief, typically in the microsecond to nanosecond range, and is followed by a longer rest period before the next pulse.
• Duration: Ultra-pulses are extremely short in duration but deliver significant energy in each pulse, allowing tissue to cool down in between.
