Ultrafast Heat Transfer Due to Femtosecond Laser Heating

Application ID: 142421


This is a simple 1D model demonstrating ultrafast heat transfer simulations for femtosecond pulsed laser heating. Specifically, the following three models are implemented and compared with conventional Fourier heat conduction (known as parabolic one-step, POS):

  • Hyperbolic one-step (HOS)
  • Parabolic two-step (PTS)
  • Hyperbolic two-step (HTS)

This model example illustrates applications of this type that would nominally be built using the following products:
