From: High-order harmonics generation in the laser-induced lead-free perovskites-containing plasmas
Harmonic spectra in the case of TCP scheme generated in two LIPs produced by FS HP. (a) HHG in MA2CuCl4 LIP. (b) HHG in MA2CuBr4 LIP. The harmonic spectra depending on the pulse duration and the sign of chirp are shown. Green filled profiles of harmonics correspond to the chirp-free 35 fs PP (Chirp-free, PD = 35 fs), red curves correspond to the positively chirped 70 fs PP (Chirp( +), PD = 70 fs), blue curves correspond to the negatively chirped 70 fs PP (Chirp(-), PD = 70 fs), black curves correspond to the positively chirped 130 fs PP (Chirp( +), PD = 130 fs), and purple curves correspond to the negatively chirped 130 fs PP (Chirp(-), PD = 130 fs).
