Diode lasers are particularly attracted to which substances?

Diode lasers are particularly effective at targeting melanin and hemoglobin due to their specific absorption characteristics. Melanin, found in skin and hair, absorbs light in the range of wavelengths emitted by diode lasers, making them suitable for applications like laser hair removal and skin rejuvenation. Hemoglobin, present in blood, also absorbs these wavelengths, allowing diode lasers to be used for procedures such as treating vascular lesions or performing certain types of surgery.

The interaction between diode lasers and these pigments is central to their effectiveness in medical and aesthetic procedures. This is because the energy from the laser is absorbed by the targeted chromophores, leading to thermal effects that can damage or alter the tissue in a controlled manner, thus achieving the desired therapeutic or cosmetic outcomes.
