Description
Summary:Generation of plasma channels by gated experimentally in details. A time-resolved low jitter ablative capillary discharges is investi- evolution and radial distributions of the electron density are measured, and proof-of-principle optical guiding experiment is conducted. A proper time window for optical guiding of a femtoseeond laser pulse is found. The generated low density, long plasma channel is believed to be useful in the applications as GeV-class channel-guided laser wakefield accelerators and compact X-ray femetoseeond coherent radiation sources.
