Abstract

The combination of the hollow fiber technique with a broadband dispersive system resulted in the compression of high energy 20-fs input pulses down to 4.5 fs and output energy up to 70 μJ. Pulse compression is achieved by a double pass through two pairs of antireflection coated fused silica prisms of small apex angle and by two reflection on a broadband chirped mirror. By increasing the input peak power of 4 GW and increasing the pressure to 1.1 bar to maintain constant Kerr nonlinearity, slightly longer pulses with twice as much energy are obtained. By using argon at 3.3 bar pressure with an input pulse energy of 140 μJ pulses as short as 5 fs, with energy up to 70 μJ are generated.
