The Science Behind Erchonia® Lasers: A Technical Q&A With Erchonia’s President

Video Summary (AI-Assisted):

Laser therapy has gained significant attention in the medical field for its potential to treat a wide range of conditions, from chronic pain to neurological disorders. However, amidst the growing interest, there’s often confusion and misinformation. To shed light on the intricacies of laser technology, Dr. Kirk Gair conducts an insightful interview with Steve Shanks, the President of Erchonia and a pioneering researcher in the field. In this seminar, we’ll delve into their technical discussion to unravel the science behind Erchonia® Lasers.

The Power Dilemma: Lower vs. Higher Milliwatts

One of the first questions Dr. Gair poses is a common one among doctors exploring laser therapy: Why does Erchonia use lower power lasers when higher power seems to be the prevailing trend?

Steve Shanks provides a compelling answer. Lower power lasers have proven to be more effective over time compared to delivering a higher dose in a single application. He cites a physics article that emphasizes the importance of energetic photons and how most of the light applied to the skin bounces off, indicating low absorption. Erchonia’s approach focuses on shorter wavelengths, not for their power but for their ability to create a photochemical reaction in cells.

Shanks explains that increasing power doesn’t equate to better results; it merely overstimulates cells and can even lead to skin heating with class 4 infrared lasers.

Understanding Electron Volts: Unraveling the Wavelength Mystery

In the conversation, the concept of electron volts (eV) emerges. Shanks elucidates that electron volts measure the energy of a photon. For example, violet lasers have 3.01 eV, while green lasers have 2.33 eV, making violet lasers 30% more energetic. This knowledge is crucial for tailoring laser treatments to specific conditions.

He emphasizes that different photochemical reactions occur with varying wavelengths. For mitochondrial stimulation, green lasers are ideal, while red lasers are effective for addressing fibrosis. To regenerate dead cells in the kidney, Shanks highlights the use of shorter and more energetic wavelengths, such as violet, which goes against the intuitive belief that more power and longer wavelengths are better.

Dispelling the Myth of Depth Penetration

Doctors are often presented with lasers boasting deep penetration capabilities. However, Shanks reveals that power alone doesn’t determine depth of penetration. In fact, Erchonia’s approach involves using more energetic wavelengths with less power delivered over time. This method, backed by extensive research, ensures that the body doesn’t trigger defense mechanisms, as observed with high-power lasers.

Dr. Gair likens this process to a domino effect, where absorption in the skin initiates a photochemical cascade that repairs tissues beyond the superficial layers.

Photobiomodulation: A Term to Avoid

A noteworthy revelation from the interview is Erchonia’s reluctance to use the term “photobiomodulation.” Shanks explains that this term implies the creation of photochemistry, whereas broad-spectrum light is photobiomodulation. Erchonia’s focus is on photochemistry, which is more effective and has a significant body of research supporting its efficacy.

Furthermore, Erchonia’s laser treatments are deemed non-significant risk studies by the FDA, emphasizing their safety and efficacy profile. This distinction sets them apart from higher-power lasers that may pose risks.

Innovative Research and Development

Erchonia’s commitment to research and development is evident throughout the interview. Shanks mentions ongoing studies involving double violet lasers for tinnitus and laser treatments for the vagal nerve, showcasing their dedication to pushing the boundaries of laser therapy.


In this illuminating conversation between Dr. Kirk Gair and Steve Shanks, we’ve delved into the technical intricacies of Erchonia® Lasers. The key takeaways include the effectiveness of lower power lasers over time, the significance of electron volts in wavelength selection, the myth of depth penetration, and the preference for photochemistry over photobiomodulation. Erchonia’s commitment to research and innovation reinforces its position as a leader in the field of laser therapy, providing doctors and patients with safe and effective treatment options.
