Efficient Terahertz Pulse Generation in Laser-Induced Gas Plasmas

With state-of-the-art amplifier laser systems one easily reaches pulse energies sufficient to ionize atoms and molecules in focused beams. If this is done in a gaseous medium at ambient pressure (e.g., in air), a plasma with a length of a few hundred μm and a diameter of up to 100 μm can be produced by a 1 kHz 150 fs Ti:sapphire laser system with laser pulse energies in the 500 μJ regime. The p...

Relativistic Electrons and Coherent Radiation

Bursts of Terahertz Radiation from Large-Scale Plasmas Irradiated by Relativistic Picosecond Laser Pulses.

Powerful terahertz (THz) radiation is observed from large-scale underdense preplasmas in front of a solid target irradiated obliquely with picosecond relativistic intense laser pulses. The radiation covers an extremely broad spectrum with about 70% of its energy located in the high frequency regime over 10 THz. The pulse energy of the radiation is found to be above 100  μJ per steradian in the ...
