| Abstract | Experiments are underway at LBNL on guiding high peak power (up to 100 TW), ultra-short (<50 fs) laser pulses using a preformed plasma channel created by an electrical discharge in a capillary. The laser beam is produced by the multi-beam l'OASIS Ti:sapphire laser system and is focused onto the entrance of the capillary using a 2 meter focal length off-axis parabola. The capillary has been developed at Oxford University and creates a fully ionized plasma channel with a radial density profile that is suitable for guiding over a length ranging from 30 to 70 mm. The laser beam is monitored using a CCD camera based mode profile diagnostic, an optical spectrometer and a pulse length diagnostic. Experimental results will be presented on the plasma channel characteristics and on laser guiding and its dependenceo n laser and channel parameters. |
