What wavelength range is typically utilized by Class IV lasers?

Class IV lasers are typically utilized in the wavelength range of 800-1000 nm because this range effectively penetrates tissue and is optimal for therapeutic applications. The wavelengths in this range are absorbed well by water and hemoglobin, leading to effective photobiomodulation—the process by which light energy is absorbed by cells to enhance healing and reduce pain.

This wavelength range also offers a balance between penetration depth and efficiency; lower wavelengths may not penetrate as deeply, while higher wavelengths might be less efficiently absorbed by the target tissues. This is crucial in therapeutic settings where effective energy delivery to deeper tissues is necessary for optimal treatment outcomes. Thus, utilizing lasers in the specified range of 800-1000 nm allows practitioners to harness the full benefits of the laser for conditions ranging from musculoskeletal injuries to chronic pain management.
