Wavelengths
Wavelength is one of the most critical factors in determining the effectiveness of photobiomodulation (PBM) and cold laser therapy. Each wavelength interacts with tissue in a unique way, influencing penetration depth, cellular response, and therapeutic outcomes.
Widely considered the most effective wavelength for deep-tissue therapy.
Penetrates deeply into tissue while maintaining strong cellular interaction.
Stimulates mitochondria, increasing Cytochrome C Oxidase and ATP production.
Found in ~70% of professional therapy lasers for its balance of depth and efficacy.
Known for its ability to heat tissue water content, stimulating blood flow.
Excellent for pain-focused treatments, especially when paired with other wavelengths.
Energy is primarily absorbed thermally — ideal for immediate relief.
Effective for reducing inflammation through deep thermal effects.
Relieves chronic pain, reduces tension, and enhances circulation.
Converts light energy into heat, calming inflamed tissue.
Highly effective for nerve stimulation and oxygenation.
Supports circulation and calms nerve irritation.
Interacts with hemoglobin and membranes to boost mitochondrial function.
Delivers high-energy photons for skin-level and antibacterial use.
Supports wound healing, acne treatment, and immune modulation.
Triggers ROS and nitric oxide release to promote repair and disinfection.
Red light ideal for surface-level tissue and skin appearance.
Improves microcirculation and reduces visible irritation.
Stimulates cellular repair in the outer layers of tissue.
Understanding Laser Therapy Power & Delivery Modes
The ReGen Advantage
ReGen represents the forefront of laser therapy design. It gives users precision control with the ability to isolate individual wavelengths and adjust power levels per wavelength. This ensures more targeted treatments and better outcomes.
Unlike generic systems, ReGen is equipped with built-in safety technology to prevent overuse or accidental misuse. It intelligently monitors output to protect both the user and patient — making it one of the smartest and safest high-power lasers available.
Power Matters
In laser therapy, power determines how quickly results can happen. A higher-powered laser delivers more energy in less time, which means:
- Shorter treatment sessions
- Faster biological responses
- More efficient therapy overall
Lower-power devices may still offer benefits, but they often require longer treatment times and may delay outcomes.
Average Power
Average power is the single most important specification when evaluating a laser system. It defines how much energy is actually delivered during use.
- High average power = more energy in less time
- Low average power = slower, less effective treatment
While many brands highlight features like pulsing, the average power is what drives real therapeutic effect.
SuperPulse Limitations
Some low-power lasers use SuperPulse mode to create short, high-intensity bursts of light. These may sound impressive, but the average power remains low.
- A laser may advertise 15W peak power
- If the pulses are brief, average power stays under 1W
- Low energy delivery = minimal therapeutic effect
Peak Power Misleading
Some manufacturers advertise only peak power (e.g., “300W!”) but omit the true average power, which may be under 0.1W.
- True value comes from sustained energy output
- Flashy peak specs can be misleading
- Insufficient average power leads to longer and less effective treatments
Pulsing Hype
Terms like “Intense SuperPulse” may sound innovative, but they are often just repackaged standard pulsing. They rarely result in higher energy delivery.
- Low average power is still the limiting factor
- Advanced marketing ≠ better clinical outcomes
What to Look For
- Clearly stated average power output
- Consistent, sustained energy delivery
- Transparent specifications — not just flashy claims
Pulsing
Laser therapy can be delivered in Continuous Wave (CW) or various pulsed modes, depending on the goals of the treatment. Both modes have valid uses — and the most effective systems offer full flexibility between them.
Continuous Wave (CW)
Continuous Wave is a steady, uninterrupted stream of light. It is often preferred when the goal is to deliver a high total dose of energy in a shorter period.
CW is particularly useful for:
- Neuropathy treatments
- Chronic inflammation
- Large muscle groups or joint areas
It offers deep, consistent stimulation and is the foundation of many successful protocols, including those used in physical therapy and veterinary medicine.
Pulsing and Duty Cycle
Pulsing introduces light in repeating on/off cycles defined by a duty cycle — the percentage of time the laser is “on” during a set interval.
- A 10% duty cycle means the laser is active 10% of the time
- Lower duty cycles reduce heat and allow for longer sessions
- Pulsing can produce beneficial effects at lower average power
Pulsing is often used to:
- Target neurological pathways
- Avoid overstimulation
- Apply low-level energy in more controlled patterns
Common Therapeutic Frequencies
Therapeutic pulsing frequencies have been studied and used extensively in clinical settings. Different frequencies may interact with different cellular systems or therapeutic goals.
Common frequencies include:
- 10 Hz – often used for nerve-related applications and neuropathy
- 40 Hz – associated with neurological synchronization and cellular communication
- 73 Hz – commonly used in protocols based on Nogier research
- 292 Hz – linked to muscle and tendon support
- 1000–3000 Hz – often used in musculoskeletal protocols for comfort and thermal control
There are also classical frequency sets such as:
- Nogier Frequencies – based on European neuromodulation research
- Bahr Frequencies – used in microcurrent and acupuncture-based protocols
- Custom protocol stacks – built by therapists to layer different effects
