Abstract

A scheme for stable shot-to-shot few-cycle pulse production has been realized by launching an initially collimated laser beam into a gas tube. We found that the optimum parameters for the sevenfold compression of 55fs, 5mJ, Ti:Sapphire laser pulses are the following: 0.80.9atm argon gas pressure and the registration aperture with a diameter of 300700μm. A technique for the efficient extraction of the self-compressed pulse from the desired position along the filament has been provided by moving the registration aperture along the tube. With this technique, pulses as short as 8fs were detected at a distance of 1m from the filament starting position, in agreement with numerical simulations performed using a 3D+time axially symmetric code.
