    Laser irradiation of tissue shows minimal heat transport from blood flow. Temperature measurements align with a 1D model, informing laser applications in medicine.

    Area of Science:

    • Biomedical optics
    • Thermal effects of lasers
    • Tissue optics

    Background:

    • Understanding laser-tissue interaction is crucial for medical applications.
    • Accurate temperature prediction during laser procedures is essential for safety and efficacy.
    • Laser parameters like wavelength and tissue properties influence thermal response.

    Purpose of the Study:

    • To measure temperature rise in living and dead tissues during Ar+- and Kr+-laser irradiation at various depths.
    • To quantify the contribution of blood flow to heat transport.
    • To investigate the influence of penetration depth and backscattering on thermal effects for different laser wavelengths.

    Main Methods:

    • Irradiation of living and dead tissue samples with Argon (Ar+) and Krypton (Kr+) lasers.

  • In-situ temperature measurements at different tissue depths.
  • Comparison of experimental data with a one-dimensional thermal model.

    • Main Results:

    • Blood flow contribution to heat transport during laser irradiation was found to be minimal.
    • Experimental temperature measurements showed reasonable agreement with the one-dimensional model for temperatures below 100°C.
    • Differences in penetration depth and backscattering were observed between blue-green Ar+ and red Kr+ laser radiation.

    Conclusions:

    • The study provides valuable data on laser-induced thermal effects in biological tissues.
    • The findings support the use of simplified one-dimensional models for predicting tissue temperature under specific laser irradiation conditions.
    • Results offer insights for optimizing laser parameters in medical treatments to minimize thermal damage.
