Generation of submicrojoule high harmonics using a long gas jet in a two-color laser field

We have achieved very efficient high-harmonic generation in a two-color laser and target conditions, strong harmonics were produced at 2(2n+1)th orders in an orthogonally polarized two-color field. The str...
