Nonlinear optics in the extreme ultraviolet
Article Abstract:
The study presents the generation of intense isolated pulses from a single harmonic by using a sub-10-femtosecond blue laser pulse, producing a large dipole moment at the relatively low harmonic order nonadiabatically. Further the extreme ultraviolet (XUV) pulses durations of 950 attoseconds and 1.3 femtoseconds were characterized by an autocorrelation technique, based on two-photon above threshold ionization of helium atoms.

Strong second-harmonic generation from centrosymmetric dyes
Article Abstract:
A new study describes a strong second-order nonlinear optical signal in an ultra-thin film made of centrosymmetric squaraine dyes. The results are considered revolutionary because significant even-order effects are known to occur only in non-centrosymmetric media. It opens up new possibilities for nonlinear optical signals, which are the main components of modern optical communications systems.
