High-order harmonic generation in a gas-filled hollow fiber

Summary form only given. We report high order harmonic generation (HHG) (11th-27th) in a hollow fiber. The laser pulses used in this study were generated by a CPA-based Ti:sapphire laser producing the 80-fs pulses with 4 mJ at a 10-Hz repetition rate. The amplified pulses were focused to 90 /spl mu/m in diameter with an achromatic lens just behind a pin hole of a static gas cell in a vacuum chamber.
