The CO2 laser, with a wavelength of 10,600 nm, is particularly effective for soft tissue procedures due to its high absorption by water, which is a significant component of soft tissues. The absorbed energy causes rapid vaporization and coagulation of the tissue, making it an excellent choice for cutting and sealing soft tissues with minimal thermal damage to surrounding areas. This selectivity is important in surgical applications as it enhances precision and reduces recovery times.

While the other wavelengths have their own applications—such as the Er:YAG laser's affinity for water, which is critical for ablative procedures, and the diode or Nd:YAG lasers being useful in specific contexts—the CO2 laser’s properties make it the most suitable option for soft tissue work in terms of efficiency, control, and minimal collateral damage.
