We report the amplification of 250 GHz pulses as short as 260 ps without observation of pulse broadening using a photonic-band-gap circuit gyrotron traveling-wave-amplifier. The gyrotron amplifier operates with a device gain of 38 dB and an...
High-speed single-shot optical focusing through dynamic scattering media with full-phase wavefront shaping [0.03%]
利用全相位波前整形技术实现高速单次透过动态散射介质光学聚焦
