Tilted Femtosecond Pulses For Velocity Matching In Gas-Phase Ultrafast Electron Diffraction, Ping Zhang, Jie Yang, Martin Centurion
Tilted Femtosecond Pulses For Velocity Matching In Gas-Phase Ultrafast Electron Diffraction, Ping Zhang, Jie Yang, Martin Centurion
Martin Centurion Publications
Recent advances in pulsed electron gun technology have resulted in femtosecond electron pulses becoming available for ultrafast electron diffraction experiments. For experiments investigating chemical dynamics in the gas phase, the resolution is still limited to picosecond time scales due to the velocity mismatch between laser and electron pulses. Tilted laser pulses can be used for velocity matching, but thus far this has not been demonstrated over an extended target in a diffraction setting. We demonstrate an optical configuration to deliver high-intensity laser pulses with a tilted pulse front for velocity matching over the typical length of a gas jet. A …
