Frequency-angular distribution for terahertz emission of single-color laser filament plasma under an electrostatic field
نویسندگان
چکیده
Frequency-angular distributions for THz emission in the range of 0.1 - 3 generated a single-color laser filament plasma situated both under and without electrostatic field are first time experimentally studied. The angular distribution various spectral components this is demonstrated to differ significantly. maximal propagation angles these grow up electric field, low-frequency depending significantly on pulse energy contrast case no field. An increase leads decrease disappearance local minimum axis.

متن کاملTerahertz laser frequency combs
The development of optical frequency combs has had a revolutionary impact on high-precision metrology and spectroscopy, and the development was recognized with a Nobel Prize in 2005. At visible and near-infrared frequencies, the combs are often formed based on mode-locked lasers whose periodic pulse trains in the time domain naturally lead to frequency combs from the duality relation in Fourier...
متن کاملUltrabroad Terahertz Spectrum Generation from an Air-Based Filament Plasma.
We have solved the long-standing problem of the mechanism of terahertz (THz) generation by a two-color filament in air and found that both neutrals and plasma contribute to the radiation. We reveal that the contribution from neutrals by four-wave mixing is much weaker and higher in frequency than the distinctive plasma lower-frequency contribution. The former is in the forward direction while t...
متن کاملNumerical Simulation of an Intense Isolated Attosecond Pulse by a Chirped Two-Color Laser Field
We investigate theoretically the high-order harmonic spectrum extension and numerical generation of an intense isolated attosecond pulse from He+ ion irradiated by a two-color laser field. Our simulation results show that the chirp of the fundamental field can control HHG cutoff position. Also, these results show that the envelope forms of two fields are important factors for controlling the re...
متن کاملObservation of terahertz emission from a laser-plasma accelerated electron bunch crossing a plasma-vacuum boundary.
Coherent radiation in the 0.3-3 THz range has been generated from femtosecond electron bunches at a plasma-vacuum boundary via transition radiation. The bunches produced by a laser-plasma accelerator contained 1.5 nC of charge. The THz energy per pulse within a limited 30 mrad collection angle was 3-5 nJ and scaled quadratically with bunch charge, consistent with coherent emission. Modeling ind...
