Crystallization of strongly interacting photons in a nonlinear optical fiber
... techniques. The confinement enables the generation of large, tunable optical nonlinearities via the interaction of photons with a nearby cold atomic gas. In its extreme, we show that a quantum light field can undergo fermionization in such one-dimensional media, which can be probed via standard phot ...

Measurement of the THz emission from a femtosecond laser filament
... laser filament in air is measured with a bolometric detector and a set of filters, confirming that the main part of the emission lies between 0.5 and 3 THz. The efficiency of this THz emission is compared with that obtained in air via Four Waves Mixing of femtosecond laser pulses at ω and 2 ω in the ...
