WHILE existing research on material properties rarely examines changes in laser pulses, or the flashes of laser lights, over time, scientists from the University of the Philippines Diliman-College of Science (UPD-CS) approached laser exploration differently by investigating how non-Gaussian lasers affect the diffusion of heat in metals.

In their recent study, Jenny Lou Sagisi and Dr. Lean Dasallas of the UPD-CS Materials Science and Engineering Program (UPD-CS MSEP), along with Dr. Wilson Garcia of the UPD-CS National Institute of Physics (UPD-CS NIP), investigated the effects of different temporal laser source terms (TLSTs), or shapes of the laser pulses, on simulating heat diffusion in metals.
