The dielectric permittivity of Pb(Zr 0.52 Ti 0.48 )O 3 (PZT) ceramics as a function of temperature was measured in the frequency range from 1 to 10 kHz. There exists a dielectric loss peak close to and below the Curie point, the height of which decre

We demonstrate a high-repetition-rate soliton fiber laser that is based on highly-doped anomalously-dispersive erbium-doped fiber. By splicing an 11-mm single mode fiber to the erbium-doped fiber, thermal damage of the butt-coupled saturable Bragg re

Supercontinuum generation is observed in highly nonlinear bismuth-oxide fiber with normal dispersion. The small effective area and high nonlinearity allow generation of smooth, spectrally-unstructured spectra from 1300 nm to > 1700 nm with sub-0.5 nJ
