Hawking radiation from ultrashort laser pulse filaments.
نویسندگان
چکیده
Event horizons of astrophysical black holes and gravitational analogues have been predicted to excite the quantum vacuum and give rise to the emission of quanta, known as Hawking radiation. We experimentally create such a gravitational analogue using ultrashort laser pulse filaments and our measurements demonstrate a spontaneous emission of photons that confirms theoretical predictions.

Cavity Optical Pulse Extraction: ultra-short pulse generation as seeded Hawking radiation
We show that light trapped in an optical cavity can be extracted from that cavity in an ultrashort burst by means of a trigger pulse. We find a simple analytic description of this process and show that while the extracted pulse inherits its pulse length from that of the trigger pulse, its wavelength can be completely different. Cavity Optical Pulse Extraction is thus well suited for the develop...
متن کاملComment on "Hawking radiation from ultrashort laser pulse filaments".
In a recent paper [1] Belgiorno et al claimed to have observed the analog of the Hawking effect created by light pulses in silica glass because of the detection of radiation in a frequency range in which what they called " phase horizons " existed. Unfortunately, while the observations are very interesting, the cause of the radiation is not understood, and we feel it is not justified to call th...
متن کاملUltrashort laser pulses and electromagnetic pulse generation in air and on dielectric surfaces.
Intense, ultrashort laser pulses propagating in the atmosphere have been observed to emit sub-THz electromagnetic pulses (EMPS). The purpose of this paper is to analyze EMP generation from the interaction of ultrashort laser pulses with air and with dielectric surfaces and to determine the efficiency of conversion of laser energy to EMP energy. In our self-consistent model the laser pulse parti...

Nanocomposite materials, including noble metal nanoparticles embedded in a dielectric host medium, are interesting because of their optical properties linked to surface plasmon resonance phenomena. For studding of nonlinear optical properties and/or energy transfer process, these materials may be excited by ultrashort pulse laser with a temporal width varying from some femtoseconds to some hund...
متن کاملUltrashort laser pulse filamentation from spontaneous X-Wave formation in air.
The description of ultrashort laser pulse filamentation in condensed media as a spontaneous formation of X waves is shown to apply also to filaments generated in air. Within this framework, a simple explanation is brought for several features of the filament such as the subdiffractive propagation and the energy flux from the weakly localized tails of the X-waves to the intense core.
