SUMMARY We have studied self-absorption effects of a laser-produced plasma (LPP) source at 6.x nm as a function of laser pulse duration and viewing angle. The spectral profiles are shown to have a strong dependence on the viewing angle. Absorption ef

2017 42nd International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz).
Numerical and experimental demonstrations are presented to reduce the distortion induced by intense terahertz field in a cross-polarized terahertz time-domain spectroscopy system. A quarter-wave plate is used to increase the initial birefringence of

Radially polarized intense terahertz (THz) radiation is measured experimentally behind a thin foil irradiated by ultrashort relativistic intense laser pulse of ultrahigh contrast. As the target thickness is reduced from 30 to 2 μm, the energy of the

Electrostatic wave streamers are excited in an inhomogeneous plasma by a resonant disturbance generated by a mesh antenna biased with an oscillating signal. These low-frequency streamers are observed to move away from the mesh antenna through the und
