Manipulation of supercontinuum generation by stimulated cascaded four-wave mixing in tapered fibers
Tailoring supercontinuum generation is important for a number of applications. Stimulated four-wave mixing in tapered optical fibers can lead to modified initial conditions for the evolution of supercontinua. ...

Chirp-controlled soliton fission in tapered optical fibers
Manipulation of the input pulse chirp during supercontinuum generation in tapered fibers provides precise control of the soliton fission process taking place in the taper waist. Simulations and experiments dem...

Characteristics of supercontinuum generationin tapered fibers using femtosecond laser pulses
Drawing single mode fibers over a flame generates tapered fibers with waist diameters of approximately 1–3 micrometers and waist lengths of up to 90 mm. We demonstrate how the profile of such tapered fibers ca...

A new powerful source for coherent VUV radiation: Demonstration of exponential growth and saturation at the TTF free-electron laser
We present experimental evidence that the free-electron laser at the TESLA Test Facility has reached the maximum power gain of 107 in the vacuum ultraviolet (VUV) region at wavelengths between 80 and 120 nm. At s...
