From: Enhanced XUV harmonics generation from diatomic gases using two orthogonally polarized laser fields
Spectra of XUV harmonics generated in N2 using (a) Single-color field (\(\omega\)) at the wavelength of 1030 nm; and using (b) Two-color field (\(\omega\) + 2 \( \omega\)) using orthogonally-polarized 1030 and 515 nm pulses. The SH pulses with 2.8% conversion efficiency were generated in 0.1-mm thick crystal. Laser intensity in the gas jet was 2.1 × 1014 W/cm2, and gas pressure was 200 mbar. The dotted arrows (red, green, and blue) show the shift of the position of DAPM enhanced harmonics at different energies of two-color field.
