Supercontinuum Generation in Gases

Physical Review Letters, 1986
This paper describes the first observation of supercontinua from gaseous media. The supercontinuum was generated at pressures as low as 1 atm from Xe and with input power as low as 5 µJ in 40 atm Xe and 25 µJ in 40 atm CO2. Continua were produced in the rare gases, Ar, Kr and Xe and molecular gases, H2, CO2 and N2.

Supercontinuum generation by the modulation instability

Optics Communications, 2005
We report on a numerical study of supercontinuum generation in a single-mode optical fiber by the modulation instability. An ultrabroadband octave-spanning continuum is generated for femtosecond pulses with subkilowatt peak power. In particular, we investigate the influence of higher-order effects such as third- and fourth-order dispersion, self ...

Optical characteristics of supercontinuum generation

Optics Letters, 1990
Experimental evidence is presented that the supercontinuum generated in H2O or D2O is a surface phenomenon whose origin is at the surface of self-trapped filaments. This is done by a comparison of the output patterns produced by spherical and cylindrical focusing lenses as well as comparison of the polarization of the incident and emitted light.

Supercontinuum generation in tapered fibers

Optics Letters, 2000
Supercontinuum light with a spectrum more than two octaves broad (370-1545 nm at the 20-dB level) was generated in a standard telecommunications fiber by femtosecond pulses from an unamplified Ti:sapphire laser. The fiber had been tapered to a diameter of :2mum over a 90-mm length. The pulse energy was 3.9 nJ (average power, 300 mW).

Towards a thermodynamic description of supercontinuum generation

2009 IEEE/LEOS Winter Topicals Meeting Series, 2008
We consider the incoherent nonlinear regime of the supercontinuum generation process in optical fibers. We show that, under certain conditions, the phenomenon of spectral broadening inherent to the supercontinuum generation may be described by simple thermodynamic arguments based on the kinetic wave theory.

Supercontinuum Generation in Water

12th International Conference on Fiber Optics and Photonics, 2014
We report efficient generation of a broadband supercontinuum (SC) in water and aqueous gold colloids upon irradiation by intense, near-infrared, femtosecond laser pulses. The SC spectra are rationalized within the framework of a phenomenological self-phase modulation model.
