The generation of up to the 33rd harmonic (λ=24.12 nm) of a Ti:sapphire laser pulse using prepulse-produced chromium plasma as a nonlinear medium was demonstrated. A steep decrease of intensity for low-order harmonics (up to the 15th order) was followed by a plateau. A considerable restriction of 27th harmonic generation was observed in different focusing conditions.

    We show experimentally that a simple optical setup is able to reduce the duration of the harmonic emission generated by “long” (many optical cycles) laser pulses. By controlling the time-dependent ellipticity during the laser pulse, one can confine the harmonic emission to a narrow...
