Here, we report the recent progress on front end developed for 100 PW-class laser facility. Using 3 stages of optical parametric chirped-pulse amplification (OPCPA) based lithium triborate (LBO) crystals, realized a 5.26 J/0.1 Hz amplified output with bandwidth over 200 nm near center wavelength 925 nm. After compressor, obtained pulse duration 13.4 fs. As compression efficiency reached 67%, this OPCPA could potentially support peak power 263 TW at repetition rate 0.1 Hz. To best our...
Ultrafast all-optical switches based on epsilon-near-zero (ENZ)-enhanced nonlinear refraction in transparent conducting oxides have achieved exciting results realizing large absolute modulations. However, broad-band, polarization-independent, and wide-angle ultrafast been challenging to produce, due the inherent narrow band, polarization-dependent, angle-dependent characteristics of ENZ effect. To this end, we propose an switch enhanced absorption corrugated indium tin oxide (ITO) thin...

As the SWCNT increases, first stack single chain, then form unusual configurations, including staggered double chains and...
