Which lasers are specifically noted for hard tissue cutting?

Erbium-doped lasers, specifically Er:YAG and Er,Cr:YSGG, are particularly notable for their effectiveness in hard tissue cutting. Their wavelength is well absorbed by hydroxyapatite, which is found in bone and dental structures. This absorption leads to efficient cutting and ablation of hard tissues while minimizing thermal damage to surrounding areas.

The Er:YAG laser operates at 2940 nm, making it particularly suited for hard tissue applications due to its precise cutting capabilities and its ability to provide a cleaner and more controlled ablation, making it ideal in dental procedures, bone surgeries, and other applications involving hard tissues.

Similarly, the Er,Cr:YSGG laser operates at a slightly different wavelength (2780 nm) and maintains similar characteristics for hard tissue interaction. The combination of these specific wavelengths with their pulse characteristics allows for the effective targeting of hard tissues without excessive heat, resulting in less discomfort and quicker healing times for patients.

Other options may mention lasers that are effective in other applications but do not have the same level of efficiency or absorption characteristics for hard tissues as the Er:YAG and Er,Cr:YSGG lasers. This makes them less suited specifically for cutting hard tissues compared to the chosen answer.
