What is the significance of the 'Class IV' designation in laser therapy?

The 'Class IV' designation in laser therapy indicates that these lasers are classified as high-power devices, which makes them suitable for therapeutic use. Specifically, Class IV lasers can emit power levels over 0.5 watts, reaching up to several thousand watts. This high power capacity enables them to penetrate deeper tissues and achieve various therapeutic effects, such as pain reduction, increased healing speed, and improved tissue regeneration.

The ability to deliver such high energy is essential for effectively treating conditions that involve deeper layers of tissue, making Class IV lasers a versatile option in medical and rehabilitation settings for therapy. Their use spans across multiple fields, including physical therapy, pain management, and even surgical applications, where precise tissue interaction is required.

As such, the high power and efficacy of Class IV lasers distinguish them from other classes, which may have limitations in therapeutic applications due to lower power outputs.
