02: DolorClast® High Power Laser
What is DolorClast® High Power Laser?
DolorClast® High Power laser’s 905nm wavelength triggers two main types of effects in the targeted area:
Analgesic effect: Kicking in 5min after the end of laser treatment and lasting up to 72h.
Anti-inflammatory effect: Decreasing acute inflammation and leading to a quick absorption of the oedema and a faster healing process of the damaged tissue.

What are the benefits of Laser therapy?
Musculoskeletal injuries are described by patients as highly painful, especially in their acute phase. Unfortunately opioid medication or sedative are still too often prescribed despite the risk of adverse events. To avoid any addictive form of pain management, EMS has developed the DolorClast® High Power Laser to offer a non-invasive, effective yet safe solution to patients suffering from acute phase or those having a low-tolerance threshold of pain.

How can a laser help in physical therapy?
905nm - the ideal wavelength for quick pain reduction and lasting healing
What is the best wavelength for laser therapy?
Wavelengths comprised between 650nm and 1350 nm are known as the “therapeutic window”. Within this frame, wavelengths penetrate deep in the tissues as they are not much absorbed by water, blood and melanin and can therefore trigger biological mechanisms.
Within the therapeutic window, 905nm wavelength has been specifically chosen for the DolorClast® High Power Laser for its ability to be less absorbed by water (and therefore oedema often characteristic of acute inflammation), blood and melanin.
Absorption of laser wavelength
905 nm allows for treatment of deep pathologies
905 nm wavelength allows for a treatment of deep pathologies by a tissue penetration of up to 120mm without a burning of the skin.
905 nm wavelength switches off nociceptors
A nociceptor (from latin “nocere” = “to harm”) is a sensory neuron that responds to damaging or potentially damaging stimuli by sending a threat signals to the spinal cord and the brain. His turn, if the brain perceives the threat as credible, it creates the sensation of pain to direct attention to the body part, so the threat can hopefully be mitigated.
905nm laser light has the property to switch off these nociceptors after only 3 minutes of irradiation1. Based on this wavelength, the DolorClast® High Power Laser provides a quick and strong antalgic effect, without having to use any pain medication.

905 nm wavelength supresses acute inflammation
905nm wavelength leads to a reduction of the amount of Prostaglandin E2 (PGE2), which is a key marker of the inflammation. Clinical research2 shows that exposing tissues to such laser light diminishes the acute inflammation thanks to the reduction of PGE2 as fast as 1 hour after the treatment. By mimicking the effect of nonsteroidal anti-inflammatory drugs (NSAIDs), without exposing patients to their side-effects and addiction, 905nm wavelength kicks off the healing process.

How does the DolorClast® High Power Laser work?
Healing at the speed of light
300 Watts Peak power
Pulsed laser delivers bursts of emission. The higher the power peak is, the deeper the laser light can reach tissues.
1.35 Watts average Power
The amount of power
delivered over time
5 to 80 Kilo Herz frequency
The amount of pulses per second. Changing the frequency changes the overall amount of energy delivered during 1s due to pulses being delivered more (or less) frequently
100 nanoseconds pulse duration
The time measured across a pulse. Changing the pulse duration changes the amount of energy delivered per pulse. A high exposure time of tissue, meaning a high pulse duration, may generate safety issues.
The percentage of time the laser is on / off. Changing the % of modulation changes the overall amount of energy delivered due to the laser being on or off.
Clinical researches1 show that therapeutic effects of laser light on pain reduction and inflammation, characteristic of acute phase of musculoskeletal pathologies, are linked to a specific wavelength: 905 nm.
In order to reach the best clinical outcomes on deep MSK disorders, the penetration depth of the 905nm laser light needs to maximized thanks to a high peak power (300W).
For tissue safety, this amount of energy needs to be delivered to the tissues wisely. A high peak power coupled with short pulse duration guarantee in-depth penetration and tissue safety.

15x more powerful
- 300 W peak power is 15 times more powerful than conventional low power lasers
- 905 nm wavelength allows for a treatment of deep pathologies by a tissue penetration of up to 120mm
- Short pulse duration of 100ns to keep the treated tissues below the thermal threshold and hence avoid risk of burns.
Guided DolorClast Therapy suggests a combination therapy approach:
Apply DolorClast® Radial Shock Waves or Focused Shock Waves:
- 5 minutes after the end of DolorClast® High Power Laser treatment for excellent combined clinical outcomes, or
- 1 hour after the end of DolorClast® High Power Laser treatment for excellent optimal clinical outcomes
