The dataset of “Broadband amplification by dual-crystal spectral cascading in a short-wave infrared ultra-intense ultrashort laser.”
Listed in ScienceDB
We presented a broadband optical parametric chirped pulse amplification (OPCPA) system based on dual-crystal spectra cascading amplification in the short-wave infrared (SWIR) region.
Description
By cascading two crystals with different phase-matching angles, the impact of gain bandwidth narrowing in OPCPA is reduced. In addition, due to the different phase-matching wavelengths, the energy backflow of the idler pulses is also mitigated, thereby enhancing the overall energy conversion efficiency of the system.
Ultimately, SWIR pulses with a full width at half maximum (FWHM) exceeding 110 nm, a near Fourier-transform limit (FTL) pulse duration of 42.15 fs, and a pulse energy of 30 mJ are obtained (25.9% pump energy conversion efficiency), corresponding a peak power of 0.75 TW. Compared to single-crystal amplification, this configuration achieves an 80 nm expansion in FWHM, the output pulse duration is reduced by >40%, the pump efficiency is increased by 17.22% and a 2.3-times enhancement in peak power is achieved.

This high-energy, terawatt-class SWIR source has significant applications in strong-field physics, including high-intensity THz and water-window X-ray generation, among other areas.
