Terahertz radiation source in air based on bifilamentation of femtosecond laser pulses.
نویسندگان
چکیده
A new terahertz (THz) source in air based on the bifilamentation of femtosecond laser pulses is reported. This THz radiation is 1 order of magnitude more intense than the transition-Cherenkov THz emission from femtosecond laser filaments reported recently and shows different angular and polarization properties. We attribute it to the emission from a bimodal transmission line created by two plasma filaments.

Fine control of terahertz radiation from filamentation by molecular lensing in air.
We demonstrate a method to control remotely the terahertz (THz) source in air based on the bifilamentation of femtosecond laser pulses. By fine tuning the time delay between the two pulses, a significant modulation of the THz intensity from bifilamentation is observed. The phenomenon is attributed to the molecule quantum lensing effect around the air molecule revival time, which changes the sep...

متن کاملCoherent Synthesis of Terahertz Radiation from Femtosecond Laser Filaments in Air
we report on the coherent synthesis of pulsed Terahertz radiation from femtosecond laser filaments organized in an array. The Terahertz intensity is proportional to the square of the number of the filaments, which provides a simple method for scaling up of the Terahertz energy with powerful femtosecond laser. Moreover, directional off-axis terahertz radiation can be achieved. This paves the way...
متن کاملSource for ultrafast continuum infrared and terahertz radiation.
A compact and stable method for generating high-intensity linearly polarized continuum mid-IR and terahertz light using ultrafast femtosecond (fs) laser pulses is demonstrated. Continuous light generation from <400 cm(-1) (12 THz, 25 microm) to >3300 cm(-1) (100 THz, 3 microm) in a sub-100 fs laser pulse is facilitated by nonlinear mixing of the fundamental, second harmonic, and third harmonic ...
متن کاملMaker fringes in the Terahertz radiation produced by a 2-color laser field in air.
The terahertz radiation produced by a 2-color femtosecond laser scheme strongly saturates and develops an oscillatory behavior with increasing power of the driving femtosecond laser pulses. This is explained by the formation of a plasma channel due to filamentation. Due to dispersion inside the filament and the Gouy phase shift, the phase difference between the 800 nm and 400 nm pulses varies a...
