Power vs. Energy

Power vs Energy

The realm of laser therapy can be a labyrinth of bewildering terminology, often diverging from its conventional meanings. This confusion stems from a lack of comprehension among many companies, who merely echo past statements without genuine understanding. Yet, amidst this perplexity, Erchonia® stands as a beacon of clarity and commitment.

If you’ve encountered the name Erchonia®, we hope one consistent theme would resonate: our unyielding dedication to comprehending laser therapy through the most stringent clinical research standards and our steadfast faith in low-level laser therapy. Unlike conventional enterprises, Erchonia® wasn’t born from a calculated marketing strategy to peddle a product. Instead, it arose from an imperative—to further explore and develop a technology that alleviated our founder’s father from pain. Our mission remains rooted in spreading this transformative technology far and wide, aiding those grappling with similar afflictions, and enlightening healthcare providers on the significance of low-level lasers.

At Erchonia®, we recognize this pervasive confusion and are committed to illuminating the path forward. The distinction between “Power” and “Energy” in laser therapy serves as a prime example of this complexity. While these terms are often used interchangeably, their meanings carry distinct significance, influencing the effectiveness and safety of laser treatments. Let us delve deeper into this critical distinction, shedding light on its implications for practitioners and patients alike.

Power vs energy in lasers


Ah, yes, the ubiquitous term in laser therapy discussions—power. We’ve all heard the comparisons: “100 times more powerful” or “10 times more potent.” But let’s break it down: power is essentially the number of photons a laser emits every second. Sounds impressive, right? But here’s the kicker: most of these conversations miss the mark on what power truly means and how less than crucial it is in laser therapy. To put it into perspective, imagine a laser operating at a wavelength of 630 nm and a power output of 5 mW. Now, let’s crunch some numbers to figure out how many photons this laser churns out every second. Using fundamental physics formulas, we determine that approximately 1.597×10^16 photons are emitted by the laser per second. That’s billions upon billions of photons buzzing around in just one second!

But here’s where it gets interesting: ramping up the power of a laser doesn’t necessarily mean better results. Why? Because no matter how impressive the photon count sounds, if the energy of those photons is too low to initiate the photochemical reaction, it’s all for naught. In essence, it’s not about “more power.” It’s about understanding the true essence of power in laser therapy—how it interacts with the body’s biology and quantum physics principles. After all, it only takes one photon to kickstart the photochemical reaction, rendering the notion of “more power” obsolete.

So, the next time you hear the term “power” thrown around in laser therapy discussions, remember it’s not about quantity, but quality. It’s about harnessing the right amount of energy, not power to ignite the healing process within the body—a concept that Erchonia® champions wholeheartedly.


Now, let’s talk about electron volts—a term that sounds like it belongs in a science fiction novel, but it’s actually a key player in the world of atomic and nuclear physics. Essentially, an electron volt (eV) is the amount of energy gained by an electron when it’s zipping through an electric potential difference—kind of like a roller coaster ride for electrons. Picture this: each electron gets a boost of energy as it accelerates from “rest” to “excited,” thanks to this electric potential difference.

But why does this matter? Well, this electrifying journey is what stimulates our cells and triggers that magical photochemical response we’re all after. In other words, it’s the spark that ignites the healing process within our bodies. So, while it may sound like something straight out of a sci-fi flick, electron volts are actually the unsung heroes of laser therapy, quietly powering the transformative effects we’ve come to rely on. And when it comes to understanding the science behind laser therapy, knowing the role of electron volts is like unlocking the secret to its success.

And here’s where Erchonia® steps in with a game-changer: multiple wavelength lasers. Each wavelength boasts its own unique electron volt (eV) output, and only precise matches of energy will kickstart those vital protein complexes within the mitochondria. We’re talking about the Electron Transport Chain (ETC), the powerhouse where all the magic of laser therapy unfolds. And guess what? It’s got nothing to do with power and everything to do with energy.

So, whether it’s understanding the intricate dance between wavelengths or unraveling the mysteries of electron volts, Erchonia® is committed to illuminating the path forward in laser therapy—because when it comes to healing, every detail matters.
