Scalar Wave Technology
A critical look at fringe claims in laser therapy
A Note About This Page
We are not reviewing a specific laser product here—we're examining the concept of scalar waves as marketed in the laser therapy industry. When it comes to fringe concepts like scalar waves, we defer to recognized experts in photobiomodulation rather than forming our own opinions.
We believe practitioners deserve accurate, science-based information to make informed purchasing decisions.
The Experts: Tunér & Hode
For fringe concepts like scalar waves, we turn to Jan Tunér and Lars Hode—two of the most respected names in laser therapy research:
Jan Tunér
Dentist and international educator in laser phototherapy. Co-founder of the Swedish Laser-Medical Society (1989). Former Membership Secretary of the World Association for Laser Therapy (2000–2010). Author of five books on laser therapy in English.
Lars Hode
Physicist specializing in optics. Founder and President of the Swedish Laser Medical Society. Fellow of the American Society for Laser Medicine and Surgery. Pioneered research on the medical importance of laser speckles (1991). Author of five books and numerous scientific articles.
Together, they authored "Laser Phototherapy: Clinical Practice and Scientific Background"—a 938-page definitive text with 2,500 scientific references, widely considered the authoritative resource in the field.
What the Experts Say
From Tunér and Hode's published review on scalar wave claims:
"No laser equipment designed for laser photo-therapy is producing scalar waves and again, even if such waves existed, there is no evidence whatsoever that they should have a positive or negative effect on cell functions."
"Both claims are characterized by gross exaggeration, demonstrating either complete ignorance or deliberate misapplication of the science of optics."
— Jan Tunér & Lars Hode, Swedish Laser Medical Society

What Are "Scalar Waves"?
In legitimate physics, a scalar wave is simply a wave described by a scalar quantity (like sound pressure waves) as opposed to a vector quantity. However, in the alternative medicine world, "scalar waves" have taken on an entirely different meaning.
Proponents of scalar wave therapy devices typically claim their products can:
- "Dissolve cellular memory"
- "Access the quantum neutral unified field state"
- "Optimize anti-aging capabilities"
- "Activate higher dimensional subtle body functions"
- Penetrate through clothing and even the entire body
These claims draw on language from quantum physics but apply it in ways that have no basis in established science. The marketing often invokes Nikola Tesla and references to "quantum effects" to lend an air of scientific legitimacy.
⚠️ The Science Problem
Here's what the physics actually says:
Electromagnetic radiation (including laser light) consists of transverse waves with both electric and magnetic field components—these are vector quantities, not scalar.
While high-energy particles like x-rays can pass through tissue, the low-energy photons from therapeutic lasers are physically incapable of penetrating through that much tissue—and certainly not through clothing.
There is no scientific evidence that cells store "memories" in a way that could be "dissolved" by any form of light, nor any proposed mechanism for how this would work.
While laser light production does involve quantum mechanical effects, this doesn't translate to "quantum healing" or accessing "unified field states." These terms are scientifically meaningless in this context.
As one physics analysis noted: "Mixing science with pseudoscience is pseudoscience."
A Note on Violet & Purple Wavelengths
Some products associated with scalar wave claims also promote purple and violet wavelengths (typically 405–450nm) as having special or "magical" properties.
If you study our comprehensive laser comparison table, you'll see that approximately 98% of manufacturers operate in the Red (630–680nm) or Infrared (800–1000nm) wavelengths. This isn't an oversight—it's based on decades of research into photobiomodulation.
Why Red and Infrared Dominate
The "therapeutic window" of 600–1000nm exists because these wavelengths penetrate tissue effectively while being absorbed by key chromophores like cytochrome c oxidase in mitochondria. This is how photobiomodulation actually works—stimulating ATP production at the cellular level.
Some fringe manufacturers suggest that market leaders like Eltech K-Laser, LiteCure/LightForce, EVO Laser, and Multi Radiance are all wrong—that purple light has special properties these companies have somehow missed.
To put this in perspective: we believe purple and violet lasers are also the best wavelength for treating psychological problems in unicorns, fairies, and gnomes. For most other conditions, the jury is still out on the "magical" properties of purple light.
What Violet Light Actually Does
To be fair, violet/blue light (400–450nm) isn't completely without applications:
Violet/blue light is used in photodynamic therapy where it activates photosensitizing drugs that have been applied to tissue. The light causes a chemical reaction that can destroy targeted cells. This is legitimate medicine—but it requires a drug carrier and is not the same as photobiomodulation.
Some research suggests blue/violet light around 405nm may have direct antimicrobial effects against certain bacteria. This is an emerging area of research with potential applications in wound care and infection control.
Due to its very limited penetration depth, violet light is absorbed almost entirely at the skin surface. This limits its therapeutic applications to extremely superficial conditions.
However, there is very little peer-reviewed research supporting violet light as effective for general photobiomodulation in the way that red and infrared wavelengths have been validated over 50+ years of study.
How Photobiomodulation Actually Works
Legitimate laser therapy (photobiomodulation) operates on well-understood principles:
Photon Absorption
Light at specific wavelengths (primarily 600–1000nm) is absorbed by chromophores in cells, particularly cytochrome c oxidase in mitochondria.
ATP Production
This absorption stimulates the electron transport chain, increasing production of adenosine triphosphate (ATP)—the cellular energy currency.
Cellular Effects
Increased ATP leads to enhanced cell proliferation, reduced inflammation, improved circulation, and accelerated tissue repair.
Measurable Outcomes
These effects can be measured objectively: wound healing rates, inflammatory markers, pain scores, range of motion improvements.
This is what thousands of peer-reviewed studies have documented. No "quantum unified fields" or "cellular memory dissolution" required—just basic photochemistry and cell biology.
🚩 Red Flags in Laser Marketing
Be skeptical of any laser product that claims:
- "Scalar waves" or "soliton waves" for therapeutic benefit
- Ability to treat patients through clothing
- "Quantum healing" or accessing "unified field states"
- "Dissolving cellular memory"
- Activating "higher dimensional" anything
- Wavelengths that are dramatically different from industry standards without substantial published research
- References to Tesla or quantum physics used to explain therapeutic mechanisms
These are marketing claims, not science. Legitimate laser therapy devices don't need pseudoscientific language—they have actual research behind them.
Our Recommendation
When evaluating any laser therapy device, look for:
Legitimate devices go through regulatory review. Be wary of devices that seem to avoid or skirt FDA requirements.
Look for devices that use wavelengths and parameters supported by peer-reviewed studies, not just manufacturer claims.
Red (630–680nm) and infrared (800–1000nm) wavelengths have the most research support for photobiomodulation applications.
Reputable manufacturers provide clear power outputs, wavelengths, and beam characteristics—not vague references to "energy fields."
Companies like Eltech K-Laser, LiteCure/LightForce, Multi Radiance, and others have track records and don't rely on pseudoscientific marketing.
