Maximal terahertz emission in high harmonic generation from 3D Dirac semimetals
To increase the output intensity of conventional THz harmonic generation platforms, the medium is normally made continuously thicker. Here, 3D Dirac semimetal films are predicted to increase the THz output by orders of magnitude, but only up to an optimal thickness dictated by its nonlinear response...

| Sumario: | To increase the output intensity of conventional THz harmonic generation platforms, the medium is normally made continuously thicker. Here, 3D Dirac semimetal films are predicted to increase the THz output by orders of magnitude, but only up to an optimal thickness dictated by its nonlinear response. |
