Aspen Lasers – The Future of Laser Therapy

Class IV lasers offers better therapeutic outcome, based on six characteristics of this new technology:

• Larger dosages of therapeutic energy: Class IV lasers can deliver up to 1,500 times more energy than Class III and, consequently, reduce treatment time.
• Deeper penetration into the body: Leading Class III lasers only penetrate 0.5-2.0cm2. Class IV can penetrate up to 10cm2.
• Larger treatment surface area: Class III cover a treatment area of 0.3-5.0cm2, depending on the model and manufacturer. Class IV cover up to 77cm2. This is important when treating large regions, such as the lumbar spine, quadriceps, or hips.
• Greater power density: Power density indicates the degree of concentration of the power output. This property has been shown to play a major role in therapeutic outcomes.
• Continuous power supply: In Class III lasers, the power is pulsed or modulated approximately 50% of the time. In other words, light is permitted to pass through the probe for only 50% of the total operating time. In most cases, Class IV lasers deliver a consistent amount of energy over a given time. Their power can be adjusted for acute and chronic conditions.
• Superior fiber optic cables: Fiber optic cables transmit laser energy from the laser to the treatment probe (wand) at the end of the cable. Several studies reveal that as much as 50% of the light energy generated by a Class III laser may be lost by the time it reaches the end of the probe.
