What is peak pulse in therapeutic laser and why does it matter?

There are many factors to consider when purchasing a therapeutic laser. Wavelengths, power, source and safety classification are just a few. In this article, we look at peak power and how ASA’s MLS®️ and Hilterapia®️ devices compare to other devices on the market.

What is ‘peak power’ in therapeutic laser?

Peak power should not to be confused with Average power. Whilst Average power refers to the laser energy output per second, Peak power represents the maximum power that a laser pulse can achieve. Along with peak power, it’s important to consider the emission type as this is relevant to the safety of the laser, you can read more about this HERE. High peak power can help to deliver more photons to depth within the tissues thus delivering a highly effective treatment.

Analogy – think of a train delivering cargo to fixed points along a track. The track length is fixed as are the quantities of cargo delivered along the way. The more cargo the train starts out with, the more cargo it will have to deliver at the end of the track. In the case of laser, the track length can be considered as the depth of penetration (dependent on the wavelength of light), and the amount of cargo the peak power. The higher the peak power, the higher the energy delivered to deeper tissue.

Equipment Comparison

There are many laser devices available and trying to compare them all and decide which is most suitable for you can be overwhelming. This chart makes it easy to compare the peak-power outputs for some of the most popular class 4 diode-based lasers with the MLS®️ Mphi 75 (and M8 robotic laser) delivering 75W peak power - top of the scale in this market segment. MLS® technology at these peak powers has shown, during in-vivo and in-vitro studies, to exert therapeutic photochemical, photomechanical and photothermal effects.

Beyond this segment of the market we have addition of the higher power diode lasers with MiS, which is part of the MLS®️ laser family providing what is essentially a bridge between diode lasers and the much more powerful Nd:YAG source.

MiS offers 1000W peak power combined with MLS® patented technology to keep treatment highly effective and absolutely safe. By increasing the peak power of the device to this extent, a specific therapeutic action is achieved, the results of which can be profound: with its 1kW peak power, MiS exerts a protective action on Schwann Cells which supports the restoration of the myelin sheath and has been proven to be effective in relieving pain sensitivity in peripheral neuropathy.

Moving higher again, worldwide, football clubs, including Premier League clubs, are noticing the efficacy of the highest power therapeutic lasers available today, the Hilterapia® range from ASA. Working at a peak power of 3000W, these are the ultimate laser choice for specialist treatment when highly effective results are required in as short a timeframe as possible.

From the 25W peak power MLS®️ Mphi to the highly powerful diode 1000W peak power MiS and then up to the uniquely powerful and effective 3000W peak power Nd:YAG Hilterapia range, ASA laser top the market with peak power delivery combined with safety and efficacy.
