Which chromophores do erbium lasers primarily interact with?

Erbium lasers primarily target water and hydroxyapatite due to their specific wavelengths being strongly absorbed by these chromophores. Water is a significant component of biological tissues, and the strong interaction of erbium lasers with water allows for precise tissue ablation and vaporization with minimal thermal damage to surrounding areas. This property makes erbium lasers highly effective in various medical and aesthetic applications, such as skin resurfacing and dental procedures.

Hydroxyapatite, found in bone and dental tissues, is another critical chromophore for erbium lasers. The absorption characteristics of this chromophore enable the laser to effectively cut or modify hard tissues, making it useful in oral and maxillofacial surgeries.

This specificity for water and hydroxyapatite underscores the effectiveness of erbium lasers in procedures that require precision in both soft and hard tissues, making them versatile tools in medical practices. Other choices do not reflect the primary interactions characteristic of erbium lasers.
