Transient Hydrodynamic Lattice Cooling by Picosecond Laser Irradiation of Graphite
Jihoon Jeong, Xun Li, Sangyeop Lee +2
Recent theories and experiments have suggested hydrodynamic phonon transport features in graphite at unusually high temperatures. Here, we report a pico-second pump-probe thermal r…

Optimization of the pulse width and injection time in a double-pass laser amplifier
Daewoong Park, Jihoon Jeong, Tae Jun Yu
We have optimized the input pulse width and injection time to achieve the highest possible output pulse energy in a double-pass laser amplifier. For this purpose, we have extended…
