UP scientists explore non-Gaussian laser effects on metal heat diffusion

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.
