Ultrafast Laser Pulse Train Radiation Transfer in a Scattering-absorbing 3d Medium with an Inhomogeneity

The advent of ultrafast lasers has opened the window for many emerging applications. Specifi c applications in biomedicine include optical tomography (Yamada, 1995), tissue ablation (Sajjadi et al., 2013), tumor diagnostics (Bhowmik et al., 2014), thermal treatment (Jiao and Guo, 2009), to name a few. Recently, an excellent review on advances in the computational modeling of ultrafast radiative transfer was provided by Guo and Hunter (2013), in which advantages and disadvantages of various numerical solution methodologies have been summarized. The importance of studying the interaction of ultrashort-pulsed lasers with biological tissues and the corresponding mathematical modeling of possible thermal damage was also reviewed by Sajjadi et al. (2013). Some prior numerical investigations relevant to the present study are reviewed as follows.
