ABSTRAKT

The use of ultrafast laser technology has become widespread in recent years for many emerging applications, such as optical tomography, plasma‐mediated ablation, surgical and medical procedures, and device manufacturing and material microprocessing for both biomedical and industrial purposes. In situations where ultrafast laser experimentation is complicated or expensive, numerical modeling can be implemented as a realistic alternative. In optical imaging reconstruction, forward modeling of radiative transfer under various conditions is indispensable. To determine radiant energy propagation with ultrafast speed of light, an accurate solution of the time‐dependent hyperbolic equation of radiative transfer is required; and this is featured as ultrafast radiative transfer. In this review, advances in the computational modeling of ultrafast radiative transfer are discussed. Various numerical solution methodologies, along with the mentioning of their contributing works, advantages and challenges, are presented. The importance of appropriate treatment of anisotropic scattering of both ballistic and diffuse radiations is addressed. Additionally, specific applications of ultrafast laser technology in the biomedical field are presented, along with contributing works.
