Understanding Power in Laser Therapy

More usable energy in the tissue — not just more “watts” on the brochure.

• Recovery speed: higher average power can shorten treatment times.
• Depth of effect: enough energy must reach the target layer, not stop at the skin.
• Workflow: efficient power lets you treat more regions or patients without adding chair time.

Low-power systems can still work — they usually just need longer exposure and more visits.

Average power is the “cruise control” of the laser, measured in watts (W).

• Describes continuous energy delivery over time.
• Feeds directly into dosage calculations (J/cm²) and realistic depth expectations.
• Should be read alongside spot size, wavelength mix, and pulsing—not in isolation.

When in doubt, ask what average power is available at the handpiece, not just inside the box.

Microbursts of light that feel gentle on the surface but still move energy into tissue.

• Very short, high-peak pulses with long rest periods between them.
• Useful over sensitive regions, post-surgical sites, and neuro applications.
• Best results happen when SuperPulse is paired with a clear dosage strategy, not used as a magic word.

Peak power makes marketing headlines; average power delivers outcomes.

• Peak power: the very top of each pulse — impressive numbers, very short duration.
• Continuous / average power: what the tissue actually “feels” over the whole treatment.
• If only peak is advertised, ask how much real energy per second reaches the patient.

Clinically, dosing is built on average power and time, not on a split-second peak.

Pulsing is a way to shape how cells are stimulated and how heat is managed.

• Lower duty cycles can allow time for thermal relaxation between bursts.
• Different frequencies are used to emphasize comfort, circulation, or neurological emphasis.
• Advanced systems combine CW and pulsing so you can match protocols to tissue response.

A quick checklist for separating engineering from hype.

• What is the true average power at the aperture, and at which wavelengths?
• Can the system run in continuous and pulsed modes, and are frequencies selectable?
• Are there clinical protocols or outcome data that match my patient population?

Clarity on these points makes it easier to compare brands and choose a laser that fits your practice rather than the loudest marketing claim.
