(Left) Measured spectra of 1 kHz lasers available for driving the Cu tape PXS: L1 ALLEGRA with a central wavelength of 820 nm and LEGEND with a central wavelength of 795 nm. (Right) Picosecond temporal contrast of the driving lasers L1 ALLEGRA and LEGEND, highlighting a pre-pulse with intensity 10−4 at −14 ps for LEGEND and a ghost peak at −3.2 ps for both lasers. |
