| Abstract | We produce harmonics in the molecule ethylene (C₂H₄) with two different wavelengths and three pulse durations. Due to the low ionization potential (Ip = 10.5 eV) of C₂H₄, longer wavelengths are needed to extend the maximum photon energy produced. Our results show that regardless of the strong dependence of the efficiency of the harmonic generation process with wavelength, at 1820 nm the cutoff observed is larger than that obtained with 800 nm, 15 fs pulses. We obtain harmonics with energies exceeding 70 eV at 9.0 x 10¹³ W/cm² with a 73 fs 1820 nm pulse. Under these circumstances, the limiting factor for the further extension of the cutoff seems to be the phoionization cross section of the molecule. |
