Why is it important to understand the absorption characteristics of different wavelengths?

Understanding the absorption characteristics of different wavelengths is crucial because it directly influences treatment effectiveness. Different tissues absorb various wavelengths of light to varying degrees, which means that the choice of wavelength can significantly impact the outcomes of laser procedures. For example, certain wavelengths are more effective for targeting specific types of tissue, such as vascular lesions, hair follicles, or pigmented lesions. This selectivity not only enhances the efficacy of treatment but also minimizes damage to surrounding tissues, resulting in safer and more effective procedures. Hence, mastering the absorption characteristics allows practitioners to tailor their approach for optimal therapeutic results.
