Light-based modality
Dynamic Pulsed Light (DPL)
A filtered-light approach in which pulse delivery is actively controlled, rather than the spectrum alone being selected by a filter.
Dynamic pulsed light describes filtered-light systems in which the delivery of the pulse itself is actively managed, in addition to the spectrum selected by the optical filter.
What dynamic pulsed light describes
Dynamic pulsed light describes filtered-light systems in which the delivery of the pulse is actively controlled, not only the spectrum selected by the filter. It builds on the same foundation as intense pulsed light — a flashlamp source, optical filters — and adds control over how the pulse is delivered.
The distinction is best understood as two independent dimensions. Filtering answers which wavelengths reach the tissue. Pulse control answers how that energy arrives over time. A platform can be sophisticated on one axis and ordinary on the other, which is why both belong in an evaluation.
Two dimensions, not one
Buyers comparing filtered-light platforms often treat them as a single category differentiated by filter ranges. That misses half the design:
- Spectrum — set by the filter. Determines what the delivered light can be absorbed by. See narrowband filtered light for how tightly this can be restricted.
- Pulse delivery — set by the system’s control hardware. Determines how the energy in each pulse is distributed over time.
Two systems can ship identical filter sets and still behave differently, because their pulse control differs. Conversely, sophisticated pulse control does not compensate for a filter set that does not cover the applications a clinic wants to offer.
Why pulse control matters in principle
Selective photothermolysis holds that confinement depends on the relationship between how quickly energy is delivered and how quickly the target sheds heat. Pulse duration is therefore not an incidental figure — it is half of what determines whether energy stays where it lands.
A system offering control over pulse delivery gives the provider a second variable to work with alongside filter selection. How that control is used for a given patient is a provider-directed decision governed by training and clinical judgement; specific parameters are not published here.
On the DPL Elite platform
Pro 1 Laser offers dynamic pulsed light capability through the DPL Elite, distributed by Laser Equipment Global. The system is supplied with filters covering 640–750 nm, 640–950 nm, 530–750 nm, and 530–950 nm.
The DPL Elite product page documents the system’s specifications, licensing, and regulatory status, and is the authoritative source for what the device is licensed and configured to do.
Providers evaluating a specific configuration should request the current specification sheet.

FAQs
How does DPL relate to IPL?
Both are filtered-light technologies using a flashlamp source and optical filters. DPL describes systems in which pulse delivery is actively controlled as well, so the platform is defined by how the pulse is delivered in addition to which spectrum is selected.
What does the pulse control actually change?
It changes how energy is distributed over time within a pulse rather than which wavelengths are delivered. Spectrum and pulse delivery are separate design dimensions and a platform can differ on either.
Which filters does the DPL Elite use?
The DPL Elite is supplied with filters covering 640–750 nm, 640–950 nm, 530–750 nm, and 530–950 nm. The product page is the authoritative record of specifications and licensing.
