Different schemes to generate high energy filaments in the near infrared

The single filament formation is a well-established post-compression technique. One of the major limitations that is present in this technique is the throughput energy that can be achieved. We are trying to find schemes to enhance the energy coupled into the filament in a typical post-compression set-up, in order to obtain ultra-intense short pulses. We have tried two different strategies: to change the polarisation state of the input pulse and to change the input chirp. Both of them work fine in the sense that with both we have been able to increase the throughput energy of the filament above the millijoule, which seems to be the natural barrier of a traditional filament based post-compression scheme.
