Guiding of high intensity ultrashort laser pulses in plasma channels produced with the dual laser pulse Ignitor-Heater technique

We present results of experimental investigations of laser guiding in plasma channels. A new technique for plasma channel creation, the Ignitor-Heater scheme is proposed and experimentally tested in hydrogen and nitrogen. It makes use of two laser pulses. The Ignitor, an ultrashort (5x10{sup 17} W/c...

Description
Summary:We present results of experimental investigations of laser guiding in plasma channels. A new technique for plasma channel creation, the Ignitor-Heater scheme is proposed and experimentally tested in hydrogen and nitrogen. It makes use of two laser pulses. The Ignitor, an ultrashort (5x10{sup 17} W/cm{sup 2}, 75 fs laser pulse.
