Geometrical analysis of Kerr-lens mode-locking for high-peak-power ultrafast oscillators
Peiyu Xia, Makoto Kuwata-Gonokami, Kosuke Yoshioka
Ultrashort pulses from Kerr-lens mode-locked oscillators have inspired a variety of applications. The design and alignment of these laser resonators have thus far been theoreticall…

Efficient Terahertz Harmonic Generation with Coherent Acceleration of Electrons in the Dirac Semimetal Cd3As2
Bing Cheng, Natsuki Kanda, Tatsuhiko N. Ikeda +7
We report strong terahertz (~10^12 Hz) high harmonic generation in thin films of Cd3As2, a three-dimensional Dirac semimetal at room temperature. The third harmonics is detectable…
